I'm surprised they even announced it publicly, it can do nothing but make them look like a terrible place to go apply for work if they do things like yank offers. Although I guess since they aren't hiring for anything in the near future it doesn't matter but I bet this perception will persist well beyond when they start hiring again.
I wonder if this announcement was pressure from management and the board to make some public announcement for shareholders that Coinbase is doing something, anything, to cut costs and weather the crypto and tech downturn.
And for sure, if you work as a recruiter for Coinbase and still have a job... time to start tapping your network for other opportunities.
