🐧 Why so many Linux content creators on YouTube and other social media platforms say Ubuntu is bad if it is the most popular and used Linux Distro?

I have seen many Linux content creators say how Ubuntu is a bad distro and some say nobody should use it, but on the other hand it is very popular and all Linux statistics show that it the most popular and used Linux distro, most Linux desktop users in real life use it (or sometimes a distro based on it), almost all of the people I have seen in my life who use Linux use Ubutnu, and many people who know almost nothing about Linux will probably recognize Ubutnu if you show them a screenshot of the default desktop, so where did that "Ubutnu is bad, don't use it" thing came from if it is good for so many people who use Linux?
