I'm sure you'll contend it was taken out of context LOL.
Basically, it doesn't contain Stallman's rabid anti-business philosophy. For example, you could modify some Mozilla code and integrate it into your closed-source, for-sale application, but you would only have to license your modifications to the Mozilla code under the MPL. Your own code can remain proprietary.
Going the other way, IIRC you could make a closed-source module linked to the Mozilla application and sell the whole thing under the conditions above.
