This is like saying "You can just sail to Europe for your week of meetings." While it may be pedantically true, it's absolutely false from a functional standpoint for most people.

YouTube holds an absolutely dominant position in user created content. I have purchased products from many companies who post their troubleshooting video content on YouTube and only on YouTube. In many cases, those videos are literally the only content they provide. They do not provide any textual troubleshooting content.

Telling people "Just don't use YouTube" is a functionally useless piece of advice as they cannot "just not go there."

Also, I'm a paying customer of YouTube, why would I "have not right to set the terms they offer their services by?" Why is it that Google gets dictator-level control over the relationship, especially when they are operating as a monopoly?

We the People absolutely have the power to dictate terms to Google or any other company.
