A lot of the reasons why I used to root simply don't exist anymore. Personally, I haven't unlocked the bootloader or installed a custom ROM since maybe Nexus 4. Plus now, as others have said rooting your device makes most financial related apps stop working.
Nothing is. I'm currently writing this post on one. I will consider that weight is a big issue, one I wish was spoken of more than the plethora of reporters and journalists upset that Instagram, famously known for not having an iPad app, also doesn't have foldable support. I really like my Pixel Fold regardless.
Samsung's implementation of their Android skin is still pretty jank on their tablets. I wouldn't call it explicitly worse than stock, but enough things are done differently that it's noticeable.
Sync. It was the exclusive way I browsed Reddit. Having foldable support day 1 was a big push. I have no issues with supporting the developer for an app I've been using for well more than a half decade now.
