I have a Kobo, you can set it to “sideload mode” and you don’t need an account of any kind. It disables the store and all that and I never turn WiFi on so it’s completely offline.
I use Calibre, an amazing FOSS ebook manager, to sync my books to the Kobo.
Pretty much just download whatever from Anna’s Archive, throw it in Calibre and get it to fetch all the artwork and metadata if I want it and sync to the Kobo.
Calibre takes a little getting used to but it’s not too bad, it’s also extremely powerful once you learn more about it.
Every time I consider not tipping I just feel bad cause I know the workers are going to suffer for as long as it takes to make the restaurant or whatever to start paying properly.
But all the new places that now have a tip option but has never been customary to tip in the past can fuck off, don’t want to normalize that shit.
