Has this guy worked anywhere before? (Yes, it's a joke, I know who Zawinski is). I am sure there is a faction in Facebook who thinks their filter system needs an overhaul, and I'm sure this post will go on a big pile of "why" somewhere. However, if you're asking an engineer who works near (but probably not on) something to go talk to another team, you need to be somewhat polite. Because you're not asking them to do their job - you're asking them to go tell a colleague that they aren't doing theirs. You want them to spend political capital internally to make Facebook/whatever better for you instead of spending it on what they think would be best.
I don't think he's a hypocrite for using and hating Facebook. That's just life. I think he's forgotten that people, even Facebook employees, have ideas and agendas other than his own and you need to be diplomatic if you want them to serve yours.
