Yeah, but why would you care unless you're begrudgingly participating in the PHP industry? It's not your problem unless you make it your problem - i.e., if you're so against it, don't work in a PHP shop, don't take PHP contracts. Problem solved - if other people want to use lame/bad languages, who cares?
The impression I'm getting is that a segment people who hate on PHP are participating in the PHP economy because there aren't as many local opportunities in {insert language here}. To me, that's not much different from the guy who's stuck working in a "lowly" coffee shop because he can't find a job in his field of study, which of course, makes him entitled to be rude to customers and his fellow employees.
