At what point does Google open itself up to some legal risk as a result of this? I mean that it's probably possible to demonstrate that Google have made these changes in order to target a single developer whose product (they claim) threatens their ad-based revenue model. Obviously, Google controls its extension platform, but they must have some obligation to the third-party developers who supply an ecosystem of products which provide value to their Chrome users, right? And speaking of those users—forget users of uBlock for the moment, I mean everyone else—who may miss out on timely security updates to browser extensions as a result of this, doesn't Google's decision potentially harm them?
