to oversimplify into a couple points:

* people make mistakes, especially in communication—it happens! I misspeak (or often don't fully consider how people with different POVs will interpret what I say differently) all the time, personally

* nearly mozilla's entire remaining userbase has stuck around because of mozilla's independence and focus on privacy. everyone with a brain knows full well that selling all user data entered into the browser is the single biggest possible violation of that. therefore, how would mozilla continue to exist as a company in any capacity if that were actually the case? they would have zero users

finally, I'll leave you with hanlon's razor: "never attribute to malice that which is adequately explained by stupidity"
