I like how it is another example on how, controling the final product chipped to customer (YouTube) allow to control all the provider that come before ( MS has to switch to chromium to serve fast youtube)
Like it happened with MS: controlling the most used software, Windows, let them be able to control all pc-builder, and force them to use windows. Virtuous circle of monopoly.
YouTube can lose all the money it wants. That's not the purpose of youtube to make money as long as most people use it.
