Just a datapoint: if you "discourage" my browser, I go away and don't come back. Same with EME - I will not need your efforts in my life.
I've yet to find a site so great that I'll disable security or switch browsers to use them. (Work is an exception; somehow there's always some crappy site with needy requirements. But that's my employer's browser/computer, and the sites aren't major publishers.)
So I hope your manager did their cost-benefit well. I don't know too many publishers in a position to be selective about their readers. But I suspect I know who you're talking about, and won't personally won't miss any of their properties.
