Considering 150 million devices and their quoted "These metrics comprise 10's of gigs of data per day", let's assume 10's of gigs to be 50GB (10's of gigs is less than a hundred and more than 10, so let's go with the middle ground).

50GB spread over 150 million users comes out as ~333 bytes per user and day.

Of course, the transmission of that data is likely more bursty, but even if it transmits all the data in one go, that's only 10K per month.

So your argument about the limit doesn't really fly because even if they did charge for for that data (which they probably do), considering a limit of 1GB per month, those 10k would be 0.001% of your monthly allowance, so it's probably not even detectable by their overcharge detection algorithm.

Now. Don't get me wrong: This kind of malware is really bad and shouldn't be on these phones, or if it is, it should be opt-in for the purpose of remote support.

It's just important that we hate it for the right reasons (security, privacy).

Except that number doesn't make sense. 333 bytes per user per day can't contain the level of information they purport to offer.

An average like that takes into account many people hardly using their phone so there is nothing much to report, or using it in a bursty manner so there is nothing to report most of the week but plenty at the weekend.

The "150m devices" claim is rather vague too. It will no doubt include devices that are no longer in use, like when a dating site claims to have X million members without mentioning the fact that all but a few thousand of them haven't logged in for many months - they can truthfully claim such devices have the software installed but that will skew the average bytes/device/day taken from the released figures downwards.

A rule of marketing (which includes selling the company to prospective employees if they are looking for them on linkedin): Never lie when you can selectively use honest statistics instead.

333 bytes is enough to send plenty of information, like your favorite apps and how long you used them. Consider something like: "com.android.browser:1.4h;1-800-HI-THERE:2.3min", which is only 47 bytes.

and keypresses too?

Since most Android phones have no physical keys...

(why mention physical keys?)
