The article isn’t very substantive. What is typical of similar organizations? What exactly is a foundation? Are there any important benefits to not having members for its mission? How is the board chosen? The article describes none of this

I think those are valid questions and if someone had a look into it, that would be great

But I think the point of the article means is that a browser that claims to be the people browser frequently ignores their user's opinions

They are bankrolled by they biggest competitor, an ad tech company, which can end any day

They receive millions a year, enough to create the best browser imaginable, pay millions to executives, and keep the browser barely competitive

Having paying members could potentially be a stable source of revenue
