Serving requests is a feature of Youtube and if they don't want to serve your client... well you didn't pay for it anyway.
It's almost dumping [1]: they gave a service away for free (even if they were losing a lot of money) just to make it unfeasible for any other company to start a competing service.
Vimeo could have been a competitor, but then they pivoted to a professional market and now that Bending Spoons bought them [2], I'm not sure they will even have a future.
