Net neutrality has been debated for decades and, as the EFF apparently still has to remind people, the entire thing conceptually goes out the window once it becomes acceptable for ISPs to start blocking content on their own volition, even if you happen to completely agree with the block. After some time building blocklists of generally understood to be nasty sites, ISPs with large entertainment interests will block piracy sites. Internet archive? Blocked. Blog which writes something nasty about them? Block. Anarchist Fedi community? Etc. That’s what the EFF is warning about.
