we are not going to uncharted territory. this has been the standard way to install applications since the beginning of time, it is only in the past 15 years that the general publi has been deemed "too dumb to save themselves"
I used to fix computers as a side hustle from ~2000-~2006. There was a lot of shit software on the market, no one knew what was good, and the public really was "too dumb to save themselves." Back then, just look at antivirus software. These days, look at VPN snake oil. What's different now is apps are more sandboxed, but new apps are just a few taps away.
