If you do not like sideloading then stop living in europe and you be stuck to old ways.
But there are benefits for then user with sideloading. Its kinda funny apple could go the way they go for so long but when microsoft had internet explorer preinstalled on windows the world was to small.
Anyway there some apps that worked great in the past that are ruined by updates like design overhaul, features worked fine suddenly removed ect. Would be lovely to get older version of said app and keep using it.
Seal is ripped off smells like a scam.
