> I don't know what the formal definitions of any of these things are, but I assume (hope?) that it's important not to equate being successful with being a monopoly by definition. If Ford came out with an amazing new car tomorrow, and suddenly 95% of new cars purchased were Fords, we probably shouldn't initiate trust-busting action against Ford on that basis alone. We want car companies to try to capture market share by making better cars.
There's an important difference between "capturing market share" and "capturing too much the market share." If Ford's going to put its competitors out of business, turn them into niche players, or even just get into a position where it can rest on its laurels for a few decades, our primary concern is no longer making sure Ford can be rewarded. Honestly, I don't see the downside of regularly breaking up a #1 player with too much market share into successors that are the #2 and #3 payers (and forcing major shareholders to divest one or the other). I want companies to be competing to get to the top, but once they get there, give them a prize for their effort and send them back down.
From my experience as a customer, Amazon's e-commerce operation hasn't improved much (e.g. their search is still as shitty as ever) and has arguably regressed in many ways (e.g. more shady products and fake reviews) in the last decade. That's pretty strong signal to me that they're not under enough competitive pressure.
Amazon's search is so bad that it's almost certainly intentional in order to get customers to look at more products. This is a great example of them using their monopoly power to increase their revenue to the detriment of consumers.
For an idea of what it could be, try the search on electronic component distributor sites like Digikey[1] and Newark[2]. They are both improving their search in order to attract more customers benefiting all customers in the process.
Try to find a 34 inch 1080p monitor with both VGA and DisplayPort inputs on Amazon and you'll find yourself reading hundreds of monitor product pages. If Amazon had serious competition you could probably find and buy one in 5 or 6 clicks, or easily determine that such a combination of features doesn't exist.
I’m skeptical that making users spend a long time trying to find the right monitor would actually be good for Amazon’s revenue or that Amazon would intentionally optimize for it. If the typical user really experienced that struggle, many would probably give up without making a purchase.
To hazard a guess, I’d speculate that apparent poor quality of search results is more likely Amazon trying to push customers toward items where Amazon earns more margin. The average customer probably just buys the first/cheapest result and isn’t going to spend hours scouring the product pages. There’s a lot of complexity in Amazon’s relationships with suppliers, fee structure, and warehouses/logistics that could affect the revenue-optimizing search ranking but isn’t obvious to the user.
Amazon deliberately leading users to a suboptimal product because they get more margin seems like exactly the sort of thing that competition should help to resolve (or at least limit). The fact that search is so bad is probably evidence of too little competition.
I have to wonder if it's fundamentally appealing to a different type of customer.
You don't window-shop Digi-key. You're pretty much buying on spec sheets alone. I want to see all 330 ohm 1/4 watt through-hole resistors, now sort by price and availability in the quantity I need, then maybe discard products that don't meet some other criteria that I can't directly filter for. There's very little chance of making a sale through a slicker marketing campaign.
Conversely, people buying a single monitor might be browsing, potentially swayed by the right language and graphics on the landing pages. I'm pretty sure those bloody finches sold more ViewSonic monitors than any other aspect of their product line. For a window-shopping customer, getting the customer to see as many of them as possible improves their chances of a sale.
On the other hand, I will concur that Amazon's search is a disaster for computer products. I suspect it's also terrible in other verticals that have clear, well-defined "faceted search" concepts, but we probably have the most experience with that one here. I suspect it may be a casualty of their broadness of categories-- why spend the labour to provide really killer search if it hasn't proven to be an impediment to sales yet?

No. Not in the economics of antitrust. There is no "too much market share" threshold. Unless consumer welfare is harmed there is no reason to complain that a firm is "too big."

So go elsewhere! That's how competition should work. Among your other alternatives are Walmart and Target, which have quite robust online operations.
The "consumer welfare" standard is a fairly recent (1980s) reinterpretation, and the switch to it happened because of large business lobbying. The original intent of American trust-busting laws was very much to prevent capturing so much market share that competition becomes irrelevant.

Consumers are harmed by a "too big" firm that's under little to no pressure to improve its products. The retort to that usually "wait a few decades until the market sorts that out," but frankly, I could be dead by then.
Another poster addressed how the "consumer welfare" standard is not so much an economic argument, but rather a legal enforcement framework. I see little mechanism for consumer welfare to be harmed by the creation of multiple successor companies that all share the same successful formula of the "too big" firm but now have to compete with one another.
