Kindle versus other e-reader

Hi! Amazon just keeps irritating me, and now they’re changing some kindle stuff I don’t like, so I’m thinking of getting a different kind of e-reader. So far my research has led me to the kobo brand, model undetermined as of yet (let me know if you have recommendations you want to share).

Main question: Libby still works on non-kindles, right?

Edit: I’m impressed by the strong eyes of all of you reading on tablets, but I’m specifically looking for the ones that do something similar to the kindle paperwhite with the screen because my eyes get tired 😅
