Re: Youtube has many uses
The corporate risk for Google, Alphabet, is that not all of this communication is going to be salubrious. Some of it will be illegal, quite probably. It's easy to imagine headlines like "Google, the paedo's friend". Pretty sure the Daily Mail has already run headlines like that...
Every instance of someone misusing Google's, or Facebook's or Twitter's or anyone else's platform is a threat to the open, pseudo-anonymous nature of those platforms. They're proving incapable of cleaning up their own networks, so something is going to give way (probably the whole business model). They ought to be very worried about that.
If they don't start adapting their business model (paid? Therefore they do actually know who their users are?) they're risking a complete crash, at least in some markets.
