The once-common practice of reverse-engineering a rival platform to make an unofficial, interoperable bridge—say, a tool that scrapes your Facebook, Twitter, LinkedIn, and other messages for a common inbox on a new, privacy-respecting service—have been effectively outlawed by anti-circumvention laws, patents, copyrights, and exotic contract theories like “tortious interference.”

Calling all copyright abolition aficionados! I saw so many of them back when their ideology would help a giant corporation, but this time it would actually help people.
