1) You don't "ask" a child molester to leave the kids alone. MS obviously wants more of a presence in the internet niche of the industry. They've allowed IE to become irrelevant for at least since 2009. They've wasted a ton of money on Edge's development, and MS needs something to make Windows 10 look like its a winner. Its a cheap way for MS to get new Windows 10 users to take a look at their new web browser, and its not like MS makes it impossible to go back to making chrome or an inferior 3rd party browser the default again.
2) Speaking as an actual firefox user, for some inexplicable reason, the CEO of firefox insists on releasing notably inferior web browsers from its previous versions at the beginning of 2015!!! They are slower than the firefox versions from the start of the year, and the older firefox versions were still noticeably slower than the competition. The only reason why the older versions were tolerable was that they weren't horribly slow like your current product! Now I frequently get odd moments when firefox seems to need to hit up the CPU, without browsing activity, and because the firefox code has such poorly implemented threading, the browser will seize up while waiting for firefox to resolve its background knitting! And that's on machines with an i7 desktop CPU, and 16GB of RAM!
3) Its a sign of extreme cluelessness when Beard thinks he can deflect from his failure as a CEO, and blame Microsoft for his incompetence. This isn't 2003; no one thinks of MS as the evil empire anymore; more like the asshole grandpa who still doesn't need a bedpan. How about securing patrons or a financing model after Google decided not to give you a free lunch anymore? How about not releasing new versions with new features that denigrate what little positive opinion firefox has left with its users?!?! Your CTO(?) had the right idea when he suggested chucking non-webkit code and starting from scratch. It sounds like unthinkable refactoring that would leave firefox dead in the water for a year, but at least you would retain your current user base!!! Instead of trying to build a McMansion on top of a crumbling foundation.
4) Since he doesn't code, the only constructive thing Beard can do at this point, is try to help find a CEO less incompetent than he is (preferably with a development background), or at least put a deadline on your resignation within 6 months, in order to force the board to find a replacement.
