It's even worse: as he himself said in his second paragraph, he has no personal experience with Tinder at all, it's all from "from speaking to people who use Tinder"!

This is the most aggravating thing, even beyond the content of his comment and the way that it implicitly insults people who are trying to use Tinder for more than hookups: people see an app/phenomenon like Tinder and make a quick simplistic judgement based on what they want to see and their moral biases, and then make sweeping pronouncements like that.
