Oftentimes there are deceiving ads for pure shitware in that app. Ads that look like legitimate errors with messages such as "Critical Android Error" "Click to repair". This is a mainstream app, by a supposedly reputable company, and it is feeding me malware ads. Why there is not some sort of vetting service for ads across all devices I do not know. So many companies seem too willing to accept a few pennies for fucking their customers. I do not mind some unobtrusive and real ads, but feed me malware whose sole purpose is to fuck naive users over and I will hate you for life.
I deal daily with people who simply do not know how they got 5 toolbars and 3 browser hijackers installed on their devices. Each one slowly reducing their security, injecting ads into search results, until finally they click on something really bad like a cryptolocker or FBI virus installer.
I do not know if the real shame is that there are companies that willingly feed this market, and accept its money, or that our government would rather spend billions tracking phone calls then preventing its citizens from getting assraped by con artists.
