Earlier quoted context omitted.
> If someone's paying you to say something, it's a conflict of interest and illegal. That already misses a huge problem though, I don't pay Mozilla for Firefox and I don't pay most online sites and services that gobble up my data and sell it off.
That's what my third paragraph was for.
I may have misunderstood you, but my read on the third paragraph was mainly that Firefox, in this case, could still have a free browser that collects and sells data. That rule would just add one more fsctor for them to consider if they ever want a paid browser, they both need a viable market and be willing to give up the option to sell data.
