Was FoundationDB a CNCF project at the time of acquisition, or in some similar incubator/umbrella? Besides, seems FoundationDB was open sourced after Apple acquired it, wouldn't mean FoundationDB get more open after the acquisition? Although development stalled no matter what so maybe doesn't matter.
FoundationDB development has not stalled; v8 is still on the way. If anything, it's mostly just been stable for a while now, and it has now been developed as open source longer than it existed as closed source.
