You can solve all the problems you describe; it just takes some setup.
>Watching TV/Movies through any device is a bother, I have to sift through all the advertisements/brand placements for that device to find anything, and most of the time it's the same 20 movies repeated over and over in every section.
Pirate streaming sites[1] are more convenient, have fewer ads, and offer more selection than commercial streaming; they are much less reliable than the following options, however. Torrents have no ads, highest quality, and the largest selection, but you have to download each file manually. Good for preservation, less convenient. Stremio[2]+Torrentio[3]+Debrid[4] allow no ads, highest quality, a large selection, and streaming. This is my preferred option—this is the Spotify of movies and TV.
>Reading on a E-device is a bother, I have to sift through all the "sponsored" books and whatever other crap the ebook reader company decides to add, and be at the whims of whatever they decide they want to do with "your" device that day.
Kindle jailbreak[5] + KoReader[6] + Z-library[7] extension allow you to seamlessly download any book you'd like, directly on your Kindle. No ads, no Amazon connections, and your subsidized device[8].
>Cell-phones are a bother, they are just devices optimized for stealing your attention, money, information, or all the above.
GrapheneOS[9] comes with zero Google services or telemetry by default, and without stock bloatware or notification spam, combined with robust permissions, it goes a long way toward making your phone feel like a tool. I recommend Olauncher[10] for a distraction-free home screen.
>Pretty much everything tech related anymore is a bother.
I feel you. All of this takes effort and knowledge that people shouldn't have to acquire just to have a decent experience with their own devices. But these options exist, they are getting better, and the more people adopt them, the less leverage companies have to keep enshittifying.
