Part of being CEO/running a business is considering all options, but it doesn't mean it will ever move beyond the ROI/risk phase. Ever read one of the risk assessments in a companies public filings? It's the same thing.
Part of being a CEO is also being the public face of the product, and knowing what to say and how.
On day one he’s put his appearance on the top of hacker news under “is Mozilla trying to kill himself?”.
Yes, the problem is that it is considered an option at all. Are they running ROIs on harvesting passwords, blackmailing users and infecting all clients with malware?
All options that are in line with the organization’s mission.
The CEO of an organization like Mozilla even considering blocking adblockers for profit is like the president of Amnesty International considering to sell lists of dissidents to the secret police.
Finally, a situation besides “are we the baddies” where a Mitchell and Webb sketch is highly relevant.
