Vimeo is losing money because they are not innovating anything beyond youtube. They also run a fairly closed off community from the rest of the Internet. People don't upload because YouTube is much more far-reaching and free to use.

The "kickstarter culture" move is usually always a bad idea for running and growing a business, companies that go the route of being subscriber funded eventually fail in highly competitive markets.

SoundCloud is doing the same thing and that is why they've lost most of their relevance to creators.

The future is in platforms that find ways to not tax and undervalue their creators, that's what the best creators will move to.
