I use SearXNG since half a year or so I think. It can be a little bit slow at times and some source engines will be deactivated temporarily. But overall its good enough for my daily use. I don't search the web too often anyway and often use the search on the services webpage directly (Steam, Wikipedia or other stuff in example). One can default to SearXNG and in some cases use DuckDuckGo or Startpage (instead Google) for alternative results.

However sometimes an instance is offline temporarily or forever (but never tested after forever, so not sure about that). In those cases I have to switch to a different instance in Firefox default search engine, which I have bookmarked a few to choose from. So be prepared.

I can understand some level of tiling the keyboard, because then your left wrist can be holding straight. But the images and videos are a bit too extreme. I personally just move the keyboard a little bit to the left side on the desk and do not tilt. I tried to illustrate this with noob art

Not really. Any customer can share GPL code, after they get it. Red Hat can't change that, if they use GPL. The issue is, from my understanding, that Red Hat can have some non GPL code to build the final product. So sharing the GPL code itself would not be enough to build a 1 to 1 binary compatible distribution.

At least at theory, because we don' know all details yet. Imagine a situation like the Chrome browser vs Chromium.

Too bad. I was interesting into the game, but then this is a nogo. Thank you for the warning.
