The neck beards that judge someone's distro choice without knowing their use cases don't represent the Linux community. Just use the best tool for the job
To be fair, most tools are pretty bad at all other jobs besides the one it was made for. Same goes for an OS. If Ubuntu is made to off ramp people more comfortable with Windows, then that's just a fine purpose for aln OS.
I use Ubuntu on most of my servers and dual boot my gaming rig with Ubuntu Desktop mainly to host LLMs. I've been a Linux user for 25 years, I remember playing around with Red Hat pre 2000. Right now though, I want a solid distro that supports lots of hardware (my network consists of x86, ARM, Oracle Cloud, SBCs, etc), has a large community for support, and isn't likely to get abandoned. Ubuntu solves that
