What many of the comments seem to be missing is that you don't need to enable javascript on all google sites, only the sign-in page. With that in mind, I don't think there needs to be as much concern as we're seeing here.
It's rare for major changes to arrive all at once. Small steps are taken, with each eventually becoming the new normal that allows another small step to be taken[2]. This isn't always intentional - each small step can seem rational at the time, in isolation.
[any replies complaining about "slippery slopes" will be ignored; the normalization of deviance does not mean change necessarily will follow, just that normalizing incremental changes allows people to support changes without noticing the larger picture]
