I don't think it's fair to characterize any given user telling the OS to
reduce the data usage as a consent to be profiled by random websites. I
would certainly not expect such information to be exposed to ad trackers
and alike. You could make the same argument for turning on low power mode
but battery level being low or having low power mode turned on may reveal
the user's socioeconomic status or user's immediate need to take
certain actions. It can lead to egregious consequences like this:
I definitely would not want to be seeing ads promoting new SIM cards or ads
for a cafe with free WiFi service nearby just because I requested my phone
to reduce data usage.
