Microsoft & Google - Communication at best
MS: look at our shiny new Youtube app!
G: We don't like it. It allows downloads and has no age restrictions, and no ads. Also, it looks nicer than our other apps.
MS: fine. We'll redesign.
MS: Look! We've made it support age restrictions, added ads, and removed downloads!
G: No, we want a web app.
MS: everyone hates web apps! FU, we're releasing this since it's better.
G: Fine, we'll just block it.
-----------------To continue it in the future:-----------------
MS: Ok, we've redone it in HTML5.
G: Blocked. We've changed our policy, and it needs to be done in Dart and rendered by Blink.
MS: Actually, we anticipated that, and we have a Dart & Blink version ready.
G: Still blocked. We've decided that everyone on your youtube dev team should have mustache and wear a funny hat each weekday.
