They were expressing their own opinion, that's not an assumption. The relevance of opinion to nonprofit organizations is mediated through donation or other forms of support.

Sure but their opinion seems informed by their flawed assumption that a large software company that makes a browser is primarily only a browser company despite that not being the reality to situation.

Why not? This isn't Oxfam, this is Mozilla. To an outsider, the assumed point for all these other endeavors was to be profitable to provide more money for browser development. When that money doesn't primarily provide for that something seems sketchy.

Mozilla has basically never been 'just' a browser company. It's probably confusing for people who don't pay attention to stuff, but it's not for the rest of us.
