Google owns Youtube, which bans people for any reason they feel like, including people for whom it had become a full-time job with their channel monetization paying the bills.
It is extremely unwise and very much against the founding spirit of the Internet to allow one company this much control, especially one that has shown itself to be censorious in the past.
Despite the ban being due to a violation of YT terms of service they lost their entire Google account.

This kind of nonsense happened rather frequently when Google+ was suspending people for using "not-real" names. The suspension extended to youtube, to gmail, and to other services.
