> There's a pointless premium panel taking up space

You can close the panel with one click on the x in the top right corner. It also shows raw dislike counts to free users, which was a requested feature.

That's fair - it's up to you whether the extension is useful enough for you to keep using or support.

Being free to use doesn't make it free to run. I still have server costs to cover, and the paid features help cover those costs. Supporting it is entirely your choice, but I do need a way to keep it running.
