This is not nearly as big of an issue as it appears…
It’s not exclusive to iOS, and there’s nothing preventing someone from making a web app that does the exact same thing…
People worry there’s going to be full malware getting released that scans your files and other app data the minute you install it… but that’s not how iOS works… that isn’t even how Android works.
They should’ve just cut the cost of ram and storage upgrades to 1/3 of what they normally cost… they’d still be making bank on them…
