Ubiquiti is a giant publicly traded company... Read about the CEO, this won't happen.

Sure. But all you can do, when deciding with whom to do business, is base your decision on what they have already done. It's not viable to refuse to do business with a company on the basis of "they might one day get bought by PE and introduce customer hostile changes".

I mean, in the NAS space with a plethora of open source alternatives, that is a viable stance.

Yeah actually, there are tons of PE-proof ways to go about building a NAS.

My "NAS" is a NUC with a couple drives plugged into it using a USB DAS. apt install zfs samba, and away you go.

At home, my "NAS" is the Linux desktop box under my desk. It's got a bunch of local drives doing ZFS things, and samba.

I could split up the functions into different boxes and build a faster LAN to connect them, but doing that wouldn't improve anything except giving me more parts to goof around with. :)
