I personally will be extremely unhappy if I no longer can run dns66, newspipe or Firefox with ad blocking on my phone.
I think I might also start spending less time on my phone, which would be a good thing for me and a terrible thing for Google (in aggregate of course).
Online advertising is a whale hunting game. There is a subset of society who genuinely are so suggestible that you can convince them they need a new truck with an online ad. They are largely a disjoint set from people with strong opinions about anything, never mind the subset of those who care deeply about the freedom to modify their devices to suit our interests rather than those of the megacorps.
