If you're coming from the likes of Lightroom or Capture One you will have to learn a very different way of working, but in return you get a lot of control over the edit.
Better is subjective, but the editing is much more powerful. However, it's also a completely different editing paradigm (largely on-rails vs. layers/nodes), so some acclimatisation is required.
As the one responsible for writing much of the FAQ, I can assure you that's not what is meant. The point is to hopefully make new users aware that they can't assume their Lightroom knowledge will help them, and thus encourage them to consult the manual or some tutorials. It's an unfortunate fact that many coming from Lightroom think they already know everything and don't have to learn anything new, but when they fail to make head or tails of darktable they conclude that the issue is that it's trash and not that they didn't bother educating themselves - and they will often loudly proclaim this on Reddit in a rather entitled manner.
But yes, the library features could do with some improvements.
OpenCL is deprecated, not unsupported, on MacOS and may be removed at some point, but it absolutely does still work for now. If you don't have OpenCL acceleration, it's a bug.
Your conclusion presupposes we buy into the "keto diet is healthy" proposition.
However, there is a preponderance of real data that fats have been demonized by the sugar industry in the past, and HGI foods (high-carb, generally) are a bigger issue.
It wasn't killed off. Support was removed from Chrome, for what appears to be rather spurious reasons, but practically everyone else are busy implementing it.
While I'm not the biggest fan of WebP, using generation loss as a metric wouldn't be an indicator of a real world scenario. I can't think of any actual instance where an image needs to be re-encoded, say, 10 times, let alone 100+ times.
While certainly an impressive effort, it's not even close to competitive yet. As is pointed out in a comment on [1] and as can be seen from the rat piss yellow in the sky, the algorithms are very much on the naive/simple side of things.
