For mobile app stores you are right, but only because they are the ONLY place most people will obtain software for their device from. You don't download binaries and install them from web sites on Android or Apple.
For desktop operating systems, I think you are probably wrong. Downloading and installing binaries from web sites is a huge cause of malware infection. And warez sites were not trustworthy at any time.
I doubt much malware has been installed via Linux package managers or by the Windows app store (if anyone actually uses that).
