For sure any stability attributed to 'buntu's are due to its Debian cake and not the canonical frosting.
Pick one of the mainstays Spatry mentioned, and learn it. I choose Debian after my initial 'distro' phase and have since doubled down, more than once. It keeps getting better and the upcoming Bullseye is a bullseye!
Having been on the other end of things the 'info coordination' won't (can't) be avoided. If we invite distro's into the way of things then we get the 'Value Added Reseller' issues of every industry. Them VAR's would like some feedback! None offer much value any more, they did much in the first decades of development, but we're no longer at that stage.
Microsoft's move are more to stay relevant to their own technology than nefarious. Their rights on things is running out and there are big players coming out with contributions for fat and ntfs. So they butt in and contribute to the kernel to save face. FOSS could choose a legally reverse engineered solution, or M$ could play ball. They're playing, good choice, even though they're somewhat 'unsportsmanlike'. It's actually similar to the gpu game, amd decided to play ball while nvidia stars in their own league. I'm very happy to have my kernel grow by 20% to include amd's code and M$'s new kernel storage drivers. For others that's all useless fat, no pun.
