> shady consideration for the money - check until proven otherwise.

I don't think that actually is correct. The Mozilla Foundation is a non-profit, as has already been pointed out above. As such, they specify a mission and then are legally forced to invest all money that they make/get into this mission.

And in their mission statement, they specify that "Individuals’ security and privacy on the Internet are fundamental and must not be treated as optional." (Principle 4 in the Manifesto).

So, they cannot legally do shady stuff. And even if that means nothing else to you, the rule with law violations still is "Innocent until proven otherwise".
