I have the same general feelings, but then I recall my years as an OSS developer and being abused by people who contributed absolutely nothing to my projects. Not money, not code, not documentation, not even grammar corrections. I'm sure anyone who's been involved with reasonably popular OSS can relate.

I am not contributing to Ubuntu in any way, and that puts it into perspective.

(I still directly contribute to OSS and release OSS projects, but absolutely refuse to engage with the least bit of hostility. Any of that is an insta-block.)

Edit: Whoah the downvotes and comments. I'm not saying that Ubuntu is doing well here. I'm trying to point out that a a vast percentage of the complainers are not paying customers, and maybe if they did pay, Ubuntu would have more incentive and resources to work more quickly.
