The licensing fee you mention is purposely fuzzy
I mean, depending on what you mean by "purposely", I just think there's no good way in general to determine the exact worth of the use of a trademark.
The restricted assets remain the same as last year: a “tax reserve fund” established in 2005 for a portion of the revenue the Mozilla Foundation received that year from the search engine providers. As noted last year, the IRS has opened an audit of the Mozilla Foundation.
Since the Corporation was founded on August 3, 2005 - this might've been the reason? Before the Corporation existed, the Foundation had to receive the money from the search engine providers directly (and the "tax reserve fund" sounds like creative accounting to hold on to that money, potentially leading to the audit), whereas later, the Corporation could hold on to it and pay taxes over it like a regular corporation does.
I’m a Mozilla fan, but I’m not a fan of income inequality, and Mozilla is contributing to it.
I'm with you here, and I'm not saying that the ratio CEO pay:employee pay is a good one. All I'm saying is that the money used to fund the CEO pay could not have been used to fund Foundation projects like Common Voice, as far as I'm aware.
