Sorry to get on one of my political hobby horses but...
We actually need to consider the possibility that yes, it is. More precisely, that the new CEO is trying to do that.
It doesn't take a grand conspiracy to join an organisation on false premises. It's totally easy. You can, today, go join a political party without agreeing with them at all, with the intent to sabotage them. Or another organization, including a workplace.
And just like some people just lie for amazingly little reason, I'm increasingly convinced some people do this. Maybe for a sense of control, maybe because they think they'll get rewarded. For every person who holds a crazy belief in public, there's probably one who holds the same belief but doesn't feel the need to let others in on it. As the world gets more paranoid, it'll get worse, open fears are the top of the iceberg.
If Enzor-Demeo ends up tanking Mozilla, there are plenty of people who will be happy with that. It's not as if his career will be over, far from it. Ask Nick Clegg or Stephen Elop. We all need to wake up to the idea that maybe the people who are supposed to be on our side aren't actually guaranteed to be unless we have solid mechanisms in place to ensure it.
I see you're familiar with Stephen Elop. Also, remember that the people who hired Elop probably hired him with the intention of making a fortune off of that destruction.
It's not that he's some secret agent or some mentally ill person who wants to destroy the company while twirling his mustache, it's that he's a person carefully chosen by people who have made large fortunes from Firefox through indirect means. He would be chosen to destroy it in a way optimized for their gain, like Elop was chosen by the board to turn Nokia into a cheap, obvious Microsoft buy, Clegg was chosen to enable the Tory government, or Sturgeon to make sure that indyref2 never happened.
Google is under no antitrust threat at all anymore. Obama judges don't believe in antitrust. Google wants to get out of paying that 500M/yr, and shitting up Firefox is a great way to do it. They'd be more than happy to throw a couple dozen of those Ms to Enzor-DeMeo or whoever will help them get that done.
How much you willing to bet that he becomes Mozilla's highest paid CEO in history, ruins the product completely, then leaves and ends up an exec at Google or some 80% owned by Google offshoot founded by a Google alum?
>ends up tanking Mozilla
No, Mozilla has been tanking for a decade already. Less than 5% of market share, and zero mobile.
