I'm not suggesting that he's not entitled to his opinion and to voice it. I just think that it's a poor justification for action, and it's also slightly troubling for someone to earnestly desire a service with which millions of people are happy to disappear because it would make that one person happy.

For all we know these persons might be even more happy NOT using the service, or using something else or better in it's place.

That's, by the way, is his whole point.

Just people people are OK using X now, doesn't mean wanting to take X down is bad, or will necessarily hurt people.
