This may be a bit sudden. But instead of heaping scorn on them, I just feel grateful for the millions they must have invested in OSS. It's unlikely they are out to hurt anybody. I'd guess the vast majority of people there, now and in the past, would love to be able to continue doing so.
So, if anyone can come up with the name for whoever bought them, a sale that was probably done with little alternatives already, then hate those peoples with all you got, got ahead[1].
But don't take it out on the people that helped you all those years. Not even if they screwed up the endgame by, maybe, being too optimistic for a week too long.
[1]: But not too many death threats, maybe. Even just for purely selfish reasons, one wouldn't want commitments to OSS become a poison pill that makes any company providing such services toxic to investors.
