Linux is really just the kernel the OS runs on. What people dislike are some of the stupid choices a distribution’s maintainers make. Like, Ubuntu used to be a great entry-level operating system for people who wanted to get into Linux but didn’t want to ditch all the things they understood from Windows or MacOS. It provided a level of comfort and ease of use. Which is great, and something the Linux community needs. But then Canonical started injecting snap package bloatware with everything and it’s just a mess. You have as little control over snap updates as you do Windows updates unless you completely disable the service, which is hardly trivial for a new user.
We have a word for these. It’s called “parasites.”
