Just found that several free programs I use on my phone switched to very aggressive advertisement model. Automatically started full screen video with sound. Or ad screen you cannot leave with “back” button. I understand they push me to buy a full version of a program. But the way they do this does not work that well. At least for me. Instead I started looking for alternatives. The funny thing is: I rather buy another app, than pay guys who push me that way.
One of 2 most aggressive app is already replaced, the second one on the way.
