I by no means wanna promote Parler, but the current situation around it nicely shows how with an #iPhone you are not really in control of your device.
Wanna install the Parler app? You can still install an APK from their website on #Android. On an iPhone? Sorry, no way.
IMHO you as a user should ultimately be in control of what you install on your device even when it may not be the best idea like Parler.
