Google employees such as Justin Schuh are aggressively defending the move on tech/security principles and denying commercial motivations, while uBlock Origin dev (Raymond Hill) says the change will cripple or kill uBO on Chrome and evil motives are its raison d'être.
It's good that mainstream media articles raise the awareness of the issue, but a good technical discussion by impartial analysts would also help.
Is it possible to fix the security issues of the existing webRequest API without deprecating it? Or by replacing it with something safer but just as powerful? There should be a simple answer to those questions.
(I'm tempted to side against Google because they keep invoking "performance issues", which is a ridiculous argument: nothing helps Chrome's performance more than efficient ad-blocking. But still, I'd like to know more.)
