You can mount the efi partition, but I don't think you can usually mount the uefi or bios. I've only ever edited vbios, and haven't done so in quite some time, but I remember needing to clamp the vbios chip. Dunno if motherboards make their bios chips more accessible, but I kinda doubt it.

Some motherboard support starting bios/uefi updates from a booted OS, so there might be a vector to be found there.

I use tumbleweed on my desktop, but run arch on a secondary machine. From experience, pacman is much faster than zypper, even on a slower machine.

Look for specialist forums for whatever I'm buying, see what they recommend. Look at the documentation available from the manufacturer, it can be a good indication, if not of quality, than of maintainability. Also, I live in a country in which you can return any product bought online for any reason 14 days after it arrived, so that helps if it turns out to suck.

Not great, still better than SMS.

OpenOffice and OnlyOffice aren't related. OnlyOffice is way closer to MS Office in look and feel.

Pretty sure they really don't like ads they don't make any money from.

I guess? Seemed pretty relevant that notifications don't really work like that anymore in current Android.

Pretty sure every app has to request notification permission now, so it's pretty easy to opt-out.

I thought it might just have been about a badly worded law, but no, at least from the translation given, the law seems pretty clear, and the opinion from the court seems extremely strange.

Because most Web traffic has become more and more concentrated on a few large platforms over the last, like, two decades.

I don't think there's a one size fits all solution. You could advertise. You could also promote some of your photos on other social media, and hope that people check out the linked site. If the content and the UX is good, some of those people will probably stay.

Generally, times are hard for independent sites, though.
