This is a perfectly valid reason to like Ubuntu, and it mirrors my own reason for preferring Mint: familiarity with an OS UI. In my case, Mint Cinnamon is the closest I could find to the Win98 user interface. Back in the old days I also had Ubuntu, but then they switched to the Unity UI and I changed to Lubuntu. That went to the pits a few years ago, so I moved on to Mint. Just like you, I also have a preference for the UI, and I suspect that very many people choose a distro based on their UI preferences. That’s the beauty of Linux: plenty of options for everyone.
Everyone who signed the petition should close their Twitter accounts. And write their newspapers that they would cancel their subscriptions if the articles quoted or embedded tweets. I didn’t sign any petition, and I’m already doing it. Well, sort of. I didn’t have any Twitter account ro close.
