Betrayal

What does this guy know about Open Source? It's not like he dedicated years of his career encouraging Microsoft to warm up to Open Source or works at GitHub to make it easier for developers using Windows to use Open Source.

Or wait, he has done all that? Next you'll tell me he's super handsome and has a beautiful family. Now you're just pulling my leg.

It feels like the people Phil's reacting to ("an industry with rather paranoid clients that contractually bar us from using Open Source software") are bad at convincing their clients.

The solution isn't "learn to use open source because it's generally a better model for collaborating on software" as Phil suggests. It's "learn to educate your clients better, so that they don't contractually obligate you to do silly things".
