Submission + - Should The MPL 2 be GPL-Compatible? (mozillazine.org)
If your project uses the MPL or a derivative, read my blog post, have a chat about it on your mailing list and let me know. I'm also making a list of projects using the MPL and a list of GPLed projects using MPLed libraries — do add your project if you fall into one of those categories!
(Note: this survey is just a survey — it's not official or binding on the MPL 2 drafting team.)
