It’s literally not though. For anyone dipping their toes into Linux for the first time Ubuntu is by far and large the best place for them to start. Cononical has made a continuous concerted effort over all these years to make Linux more accessible to the layperson and it certainly shows in Ubuntu’s user friendly-ness. It might not be the right choice for someone with more knowledge of the inner-workings of Linux, or maybe not the right choice for someone who is concerned with the issues around SNAP, but the average user and especially a new Linux user does not care about these things.
Meh, I just use Google Docs. Libre office is also usable in a pinch, but it’s a little… clunky.
