From the contributor end, I no longer trust Patreon. Their announcement email was way too much obfuscation and didn't include the bottom line up front: that my $X/mo pledges would cost me an additional service fee starting January 1, and that I would automatically be levied these fees.
That is entirely my issue with it too. They said that creators would start getting almost all of the pledged money instead of just a share of it; what they "forgot" to mention is that this is purely because they redefined what a pledge means. They silently redefined it from "the amount of money I pay per month" to "the amount of money I pay per month minus fees".
Creators would get more money of course, but purely because all patreons would start paying more money. They didn't mention that either.
