I'll add again that while this may have been true at a point (and was covertly marketed into our brains by big apple) it's just not true anymore. It's honestly scary how often i hear this and yet almost no one can say where they actually heard it.
Just this week she had to install a work app for scheduling from Googles Store and got duped into a fake clone that installed 4 other apps with repeated pop up apps emulating a signup wizard.
Those non standard androids are far far more worrying and the Google App Store is way less locked down.
If my dad was in the EU I’d have to tell him never to install an app using anything but the Apple App Store.
