If they had competition, they would not be able to get away with having no customer support. The fact their customer support (which any other company like theirs would have) is practically non-existent is proof that they are using their monopoly position to the detriment of their customers who have no choice but to use them. It’s the same as them raising their prices. Except what they do instead is instead of explicitly raising prices, they cut services so that they are themselves more and more profitable. This is a direct result of their monopoly.
YouTube and other Google properties needs to be regulated by the government. They need to reinstate competent customer support and have a viable appeal system that isn’t a black hole. They need to be explicit with what constitutes a strike or a violation, and they need to be more effective in combatting fraudulent notices of copyright violation.
