1. More users should be aware of the data collection behavior of Stylish. It’s sneaky to enable that without notifying user with changelog. I don’t mind tracking and ads, but I do want to get informed.
2. You lose user if you don’t allow them to opt out.
3. You don’t even respond to negative reviews.

Stylus is really much better. They at least fix bugs.

Not giving one-star because the developer (now company) still hosts User Styles, a good distribution site for styles. But this add-on itself deserves no star.
