There is a movement going on at XDA right now to try to rally the troops to get source code released faster. I fully support this and am passing it along here.
[OFFICIAL?]Team up against HTC for timely source code releases thread! - xda-developers
Write them, email them, call them, and tell them that they need to get source out as fast as possible. Arguably their biggest competitor, samsung, gets source as as soon as thier device hits the market. Sometimes sooner. This is what we want.
I wrote them a very lengthy email today, and am awaiting reply.
You don't have to make it all legal mumbo jumbo like the XDA OP, but let yourself be heard.
