There is no such thing as a "contract if you will to the public" nor do any "commitments" that Mozilla has made to the "public at large" (whatever those are supposed to be) constitute a contract in any legally binding sense.

Losing tax exempt status and being barred from mentioning a mission statement sound like legal, not social consequences. My impression was that the parent believed Mozilla was breaking some actual law regarding truth in advertising or something by claiming their mission was to "keep the internet open and accessible to all" while also curating plugins.

Firefox extensions are not the internet.
