One of the interesing things about this story is that there appears to be no consideration of not "updating" to a new Chrome version. The idea of user choice in "updating" is completely absent. Why cannot a user say, "V3 sounds wonderful but I will stick with V2, thank you." A user has a version of a program that works for that user (e.g., with uBlock Origin), and Google can apparently forcibly stop that user from using that working version, through a process of "automatic updates". Users must "accept" updates which makes one wonder Google can pull this off. Does it not rely on user behaviour. By accepting every "update" without question, the user is effectively consenting to being controlled.
Perhaps users will someday "wake up" to realise that so-called updates are not necessarily being remotely installed for their benefit, but for the benefit of someone else. No doubt Google has some parallel construction type explanation why users need V3, but how many folks cannot see that they are letting the fox guard the henhouse.
Perhaps if ads can be blocked, so too can updates. (IME, it's possible.)
