Darts. World champion level stuff is vaguely watchable but remove the announcer/referee's energy and it's like a bad sitcom with the laugh track removed. I was brought to a tournament as a kid and I've never been in a room where everyone was that level of bored watching random people throw a fifty or whatever for hours on end.

Windows prefers to deactivate or minimize the write cache on removable devices, most of the common Linux distros generally don't make such changes. Microsoft has a very good reason for that default: not a lot of people actually use the "safely remove hardware" option and if the cache is enabled, using and waiting for that is a hard requirement for the data to have actually made its way onto the drive.
Just the usual case of survivorship bias. The long term subscriber base of "we need to go elsewhere" gathering points is mostly comprised of people that either don't vibe with the majority destination for whatever reason, disagree that there was ever a reason to leave in the first place, or don't actually want to leave but just want to complain about the current place.
I don't think it really makes a lot of sense to look for FOSS alternatives based on country of maintainer origin when it's something popular enough to be shipped by a lot of independent Linux distros and supported by local IT consultants in more or less any country. That said, to my knowledge, lighttpd is mostly German in origin and is actively maintained. It definitively lost to nginx in the great popularity contest but I don't think it's really any worse.

Self-hostable, but it seems like an absolute behemoth of an application if their "non-production-use-only" docker-compose file is to be believed, and I couldn't find any production-ready deployment instructions on a quick skim. No obvious signs of federation and I didn't see anything on their roadmap, not sure it would make a lot of sense for this though.
There are both dumps with full history and ones that are just the current set of articles. The full dump happens once a month on the 1st, but will often take ~2 weeks to run to completion, so you probably have to look back to the April 1 2025 dump for those. The metawiki dumps page has all the info.
