&gt;You can&#x27;t charge for something if a dozen other people will offer it for free.<p>ad supported ≠ free<p>Ads being a huge privacy issue, I prefer to stay away from ad supported. Then again the mobile app ecosystem experiment is flawed as people like me saw it was a trap and stayed away from it, so the results are biased because they miss the people who actually care about privacy.
The only mobile ecosystem I experimented with was getting apk from f-droid then loading them manually on a smartphone that was never online (no wifi, no bluetooth, no 3G or later)
