Yes and no, your average end user trust the Play Store and the promised security which is why an app once it’s inside can get millions of downloads.

Compare this to trying to get your average user to
a) trust your selfhosted app and
b) succeed in installing it.

Also, I can’t find a single malware that has used f-droid as it’s primary vector.

and like the idea that this system is more secure.

I can agree that an old and buggy version of a game is no fun. But that is as true of Windows versions as Linux versions.

You seem to have much worse luck when starting linux native games than I though. I have no problem with Factorio, Oxygen Not Included or Kingdoms and Castles which I think are the only linux native games I got installed at the moment.
The thing I find much more frequently is that a game released on GOG doesn’t receive the patches and dlc that the developer release on Steam. I always have to verify that a developer actually support their GOG release as well as Steam before buying.
