The temerity of Alphabet to claim to protect users from malware/spyware, when they are known to share all of your personal information and communications with the US government (Snowden revelations), is the epitome of hubris. And, also, in the world we live in, just another Thursday.
But even ignoring this - it is not for Alphabet/Google to decide whether, and how, I want protections. I want to be able to pick a sequence of bytes and install that as an application on my phone, without Alphabet having any say in whether that happens or not, and in fact without them knowing about it. It's my phone, not theirs, and the software should help me do what I need/want, not help them provide me their often-questionable services.
It's even worse when Google believes they have a legally defensible justification that your data has been "anonymized". E.g. "anonymized" location data directly from your phone that just so happens to be accurate to the meter. Such data just cannot be anonymized.
