Same as Facebook: They got big by the Zuck sucking messages and content from MySpace - then Facebook afterwards lobbied to put laws in place to forbid this kind of 'interoperability' across platforms.
Youtube started out 'allegedly' by members of their team uploading pirated hollywood movies (because they had no content), posing as users to fall under the "user-content" policy to make the company not liable.
They are all breaking the rules all the way down, but when they make it, they know exactly what to do to fill the loopholes to prevent others to do to them what they did on others. That's big tech's ethics for you: Move fast and break things, then wall yourself in.
The YouTube thing doesn't sound right. They had a ¿10? minute video limit for a long time and it was really annoying to watch pirated stuff on there. Google Video had a lot of full movies before they bought YouTube and shut it down.
Same as Crunchyroll with pirated anime fansubs.
Did Zuck really take messages and content? I know they had a certain "interoperability tool" that conveniently only worked in one direction but I didn't know it went that far

Airbnb did the same with Craigslist posts. Reddit did the same with Digg posts. OpenAI mastered the technique by stealing basically the entire Internet.
