Out of interest, what's your 'preference' when installing apps? Personally, I go for free apps then consider 'upgrading' to any available pro versions if I find them useful. Ad supported apps I'm not too keen on but will use them as & when I need to. Ideally, I'd prefer to use apps that are free, full versions with no ad support and an option to donate as & when I see fit. It's the model that works for any number of Linux distributions/applications.
