I'm not sure what's the connection between adding the app to the store and the reliability of the application. There were scandals already connected to scam projects added to the markets. It's impossible to check everything for sure. Desktop version users already know that project is reliable. And as for the new users, a great promo has to be done.
Hmm, well, why, isn't the project being tested before it is added to the market? Although, of course, I can be wrong. As for the reliability of the application - any sober-minded user can easily figure it out on their own. All the information is on the surface.
I just meant that you should pay more attention to the history of the project, its security, etc. And Google, as a corporation, does not inspire my confidence for quite a long time.
