Even if its just 10% of your users that installed your app from MAS, that’s still a huge problem. 10% of your users you can’t ship an update to and have no easy way of moving to your self-hosted updater, that’s a major problem.

I personally prefer using MAS for such apps, since that means updates are installed automatically overnight without having to deal with other people’s annoying auto-updating software. Wish Chrome itself was in the MAS, so I didn’t have to deal with Google Autoupdater.

right but I think the Apple store is still a big market. Let's not forget that even a notarized DMG (required in the Catalina update) still shows a warning "this app was downloaded from the internet" which obviously doesn't trigger in thee apple store.
