I wanna buy an ebook reader but i don’t want any amazon or other companies shit in there, just something i can connect to my pc, pass ebooks in different formats into it and read.
Look at OnyxBoox
Your best bet for a no BS ebook reader might be this (if it where in stock): https://pine64.com/product/pinenote-developer-edition/
The PineNote won’t be in stock until the community of developers figure out a proper Linux based OS for it. I dig through the forums occasionally and they are making progress, but it won’t be soon.
Take a look at pocketbook devices. https://en.m.wikipedia.org/wiki/PocketBook_International
