Notice the “up to” in their offer. It’s likely commission based and inflated numbers to lure the developer into doing it - to trick them into thinking exactly what you’ve said here.
I’d imagine what they actually pay out after you cave is significantly lower, only then you’ve already sold out your users so you might as well leave their tracking in there.
Yep, and theres nothing to stop them from pulling the rug on you once you've given in to their strongarm tactics.
You have to hold strong here and refuse to give in on the little things or they'll make a habit of shaking you down every time they're in the neighborhood because they know you'll cooperate.
And even if they could get $240k the first year, the chances of people abandoning an extension because they are now getting spammed with ads/spyware seems like quite a factor. If my ad blocker started reporting my browser history, I would be dropping that thing like a bad habit.
