Barman has been around since 2011, released under the GPL. If it does get ruined by someone, I'll replace it in my stack or fork it for maintenance myself. I'm not very worried though.

EDB has been in private equity(PE) hands since 2019 with out managing to ruin it so far. The ownership in PE hands seems to be pretty stable, so it doesn't look like the typical pump/dump mess you often see from crappy PE money.
