Yes but all of these depend on the development team at Firefox. I don’t know what the solution is, but I do know that those three browsers would not continue if Firefox didn’t also continue. There’s still a lot of development work from Firefox.

At this point I think the safer route would be to just accept the Chromium hegemony and build a free browser from that.

Same here.

I self host photo storage, which leaves originals untouched. It’s got a parity drive. There’s a hot spare. Every night it gets backed to up two different cloud providers that both host their own hardware, on two different continents (OVH, Germany and Backblaze, US East). The entire thing gets written to two offline disks every six months, for worm protection. I run recovery exercises a couple of times a year.

It would take a dinosaur killer asteroid for me to lose access to this data.

Imagine giving all that to Apple?!
