Some salty Ubuntu fans, because MX is the top listed distro on Distrowatch. It would be hilarious if this is the real reason. A man can only dream. (Edit: I'm only joking off course.)
Even EndeavourOS and Debian are above Ubuntu. (For the last 6 months.) My theory is that most Ubuntu users don't need to search in Distrowatch anyway, but people looking an alternative for Ubuntu do. Also the site counts Kubuntu and Lubuntu and all variants as separate distributions. My gut feeling says to me that most users first use for Ubuntu, even if they look for information about Kubuntu.
That would be an explanation without script kiddies. Just because I have a good heart and faith in the community. :p (my jokes get worse every day)
Fam, people are insanely petty.... I frequent the pinephone channel rooms and I can almost predict when someone is about to post some toxic(sometimes illegal) shit there. All because someone didn't read and or doesn't have enough base Linux experience for such a janky phone and they're butt-hurt over their investment. Bless text only clients.
