What company has always promptly removed any content at the request of corporate copyright owners, but it has also pursued extensive revenue-sharing projects with those same companies.

Youtuuube, or Alphabet to be more precise.

Explanation:

Youtuuube is constantly under fire for copyright infringement, you can find movies, TV series, sitcoms, cartoons, music, etc., on Youtuuube, but if the copyright holder requests that the content is removed, they will do it fast. On the other hand, Youtuuube is not necessarily a business partner for many copyright holders, but they cannot live without it.

Remember how powerful Howard Stern was on New York's radios, and how the singers or groups had to comply with his extravagant demands in order to included in his show? Youtuuube would be somewhat of a polite and well educated Howard Stern. Studios and record companies do not like Youtuuube, but they cannot survive without it either.
