This will affect 99.999% of apps out there
I'm constantly blocking their shit in my firewall, and also removing privs/events as I see fit.
It's ridiculous. Just yesterday, I *bought* an app, from a well known reputable company, with no adverts, yet it still tried to phone home with my exact location.
A number of apps will even leave a little monitoring program running permanently, whether you use the app or not. How arrogant is that?
