>Sure it's more restrictive and yes will likely break existing adblockers, but it's probably a better model for the future. A good example why "secure system" is, in a longer run, a system with low usability, and little control by the user/owner. Right now we have ability to block URLs according to any rules, without being limited to whatever the browser author conceived. Perhaps we want to block some URLs based on context, or on content of previous communication, or whatever. Or perhaps pseudo-randomly, to emulate certain problems with the network. Switching to "more secure" approach limits us to "one true way", and precludes any smart hack we may come up in the future. It doesn't help that the change feels like attempt to squeeze out grassroots adblockers, and force people to, at best, use the ABP, which allows ad publishers to buy their way around blocks, and onto users' screens. If uBlock becomes ineffective, I fully expect ABP to be even more aggressive with monetizing access to users' screens.
