TextMate 2 is not Open Source

It comes off pretty arrogant suggesting that sniping a few bugs or features is comparable to the initial investment to write the suite. I daresay if you contributed a ton to the core it would be provided gratis to you.
Use it. Don't. Whatever.
One click. Fork. Done.
As has been adequately demonstrated: TextMate 2, as it stands today, is and shall remain open source. Anyone can compile it or fork it at any time. Furthermore, as it's licensed under GPL3, MacroMates is legally bound to leave the current code open source, and allow anyone to compile and distribute it freely.
Now, if MacroMates decides to create value-added services on top of the GPL3 distribution, and charge for it, it does not in any way make it less an open source project.

The author (or indeed anyone else) may choose to sell binaries, but they cannot include any of the code supplied by other developers under the GPL, unless they also distribute the source.
As the original copyright holders they are entitled to do whatever they like with their code, including releasing derived versions that are not licensed under the GPL v3.
You could make an argument that whatever the final TextMate2 product is, it won't truly be Free Software because there will be differences (however slight) from the code that is available under GPL v3, but as with the Internet, Free Software routes around damage - they can't ever take away the code we have, if they decide to do things we don't like, we can just carry on without them :)
they accepted code from many persons. i don't think everyone works for them.
