Microsoft's fork is meant to be temporary, experimental fork.
"This GitHub fork enables Node.js to optionally use the Chakra JavaScript engine on Windows 10, allowing Node.js to run on Windows on ARM. Our goal is to merge back into master after stabilizing this code, fixing key gaps and responding to early community feedback."
Their goal is to work on it, stabalize it, and then merge it back in once it's ready for general use. Microsoft's "fork" wasn't trying to split the community or create a permanent new path. It's to build something new for Node.js that shouldn't be in the main project until it's ready. Microsoft wasn't trying to split the community, but rather trying to take on an experimental project.
The io.js/Node.js situation wouldn't have been influenced by Microsoft's announcement. Node.js/io.js didn't necessarily have an intention of reuniting in the future and might have stayed apart. By contrast, Microsoft doesn't intend to split off from Node.js at all.
Thanks for all the explanation. I though ending something with :P - could be universally understood as a bit of irony. I'm just happy with the announcement, and used MS fork and this announcement timing for my irony-driven-comment. I'm sorry for the misunderstanding.

I'm aware publishing GIFs on HN is off-topic and I realize this might be a bit childish but I couldn't help myself, and also, you sound like a lad with a sense of humor so you might appreciate it :P
