I noted what those unintended consequences are. They are that the less knowledgeable do not understand the nuances of the criticisms. All they hear is "Firefox bad, so I'll stay with Chrome." The reason of this is the sensational behavior, not the critique itself. I personally don't want any browser to have a monopoly (or excessive control) over the internet. A global utility. Competition is needed. Firefox has a lot of issues, no one is denying this. This would be a different issue if the the bashing were equal.
But this is akin to hyper focusing on Montana's Greenhouse emissions. They're problematic (one of the highest per capita) but clearly there are bigger fish to fry (<1% of US emissions). If we focus all our efforts on Montana then Texas incidentally gains, since they are the largest contributor to US emissions. Perspective matters.
