So you're going to start completely ignoring the fact that this was not under googles control and turn it into another "android isn't open thread" huh?
Explain the different ways Android OS control has gotten tighter. Can I simply not download a Gingerbread source code anymore? Is Google preventing certain devs from using Gingerbread? Is Google putting methods to stop all methods of root or locking phones they have direct control over?

Gasp, I can download the source, I WONDER WHAT OPEN SOURCE MEANS. As for Honeycomb, yes everyone knows its still closed source. However, if you want to attempt to put some malicious reason behind it rather than an admission that the honeycomb code simply wasn't mature enough to release yet, I'm willing to listen to your hypothesis.
And explain how google changed the rules. You say things and don't explain what you mean by them. Did Google have some movie rental policy before this that they changed? Were movie rentals through Android Market allowed on rooted devices before this? I mean, if they really hated rooted phones, why not prevent them from accessing the market? Or what about Google Music, which they have direct control over, are they preventing rooted users from using that?
So yes, please explain how the rules have changed.
