Re: What are you going to do about it, Alphabet?
"I'm not convinced of that. Unless they control the entire stack of my device, what stops me from routing anything I identify as an ad to /dev/null ?"
With Marshmallow, they pretty much get you from the ground floor. Even without dm-verity, they can make the ads part and parcel with the stuff you want, so you end up with a Take It Or Leave It scenario. In other words, you block the ads, you block the content as well, leaving you empty. Leaving It basically means abandoning Android. Thing is, Apple and Microsoft, basically, the rest of the market for anyone who cares, do the same thing except maybe in other ways. If all roads lead to Tartarus and you can't go back the way you came, what do you do?
