Anecdote: I had an old co-worker who was given 6 month's notice that he'd be let go from a previous job, and his manager at the time helped him look for a new gig + gave him shining reviews and references. After the 6 month period was up, they still gave him several months of severance, even after he had found a new gig. Some companies/managers actually do care about you, and it seems like Coinbase is roughly in that court.
Getting laid off with zero warning and no severance can be a life-ruining event if it's at a bad time logistically in someone's life. It could be way worse. Always have your resume updated, and take interviews every now and again just in case.
