The article is about them cutting ties with the company after finding out the CEO of the partner company was doing something bad for privacy. Mozilla, as far as we know at this point, isn’t guilty of anything bad except maybe not thoroughly digging into the CEO of this other company’s past thoroughly enough. Mozilla was not profiting off of selling your data. They’re not even sure if the other company was directly using their “privacy” service to benefit the CEO’s data harvesting company, just that he had been doing data harvesting, and then started a “privacy” company to remove data from the data aggregating sites, like the exact ones he funded.
So, are you sure you’re clear on what happened? Because Mozilla rectified an oversight on their part after they discovered a partner company’s executive had ties to the exact industry they were supposed to be fighting.
