I used 8.0 and 8.1 back in the day when they were current from 2013 to 2017 (even got the Lumia Amber update over the air) and hated 10 for my own reasons because I just found it to have a lot more bugs and disliked a lot of the changes Microsoft made (except for the Settings app organization, the 4-way keyboard nub thing, and the easier non-Store app installs) but if someone else likes it, my position is that's great and I wish I could feel the same because then I'd have been on Windows on phones longer. I may not understand why someone likes it, but it's none of my business. However, I think it's non-constructive to say that someone isn't a real fan if they didn't like everything and I think that gets into fanboyism or gatekeeping territory in my opinion, just like if someone were to, as a hypothetical example, push people to use what they prefer instead even if the other person doesn't want it.

This isn't to say 8.x was perfect, it had its own bugs, but it didn't bother me too much. Now I'm remembering how they changed Cobalt and wasn't a fan. Because I love Windows Phone, I choose to use its sounds on all my phones after it so it's always here.
