Thanks for taking the time to write this comment. It is possible they do that, ads have become a must have now for any app and you have to pay extra just not to have them. It makes me think of the switch they did with streaming service where price keeps increasing for premium features and you have at least one "cheaper offer" with ads.
One day the option with ads will be more expensive then what the full option was at the beginning of the service.
I think corporation really became pros in term of doing the right pricing to attract maximum customers offering different package in order to maximize revenue.
I respect that ads are important in order to offer "free" service or a way to pay with data instead of dollars for people that prefer this option or don't have money to pay for it. But it is annoying sometimes and it is really getting everywhere.
