>But I don't really see what overall lessons there are here.
So many chains to keep up with. There wasn't really a lesson here. Just "Vimeo is not Evernote"?
My wider lesson unrelated to this chain is that US at will employnent sucks and we need to overhaul it. You don't create a trusting career by treating employees like toys to discard.
The US has enriched a vastly larger number of software engineers through at will employment that Europe has through making it very hard to fire people who aren't adding value.
