One could argue to the contrary; The existence (and apparent success) of scam apps like this is a clear evidence your iPhone could use a 3rd party "virus scanner" - one that would protect you from malicious "virus scanners" :p

Can they even work? It depends if iOS provides a public API for getting a list of installed apps

No. The only way would be to check "openURL" for known ones, but that's limited. Or from some webserver update a list of known scam ones and just tell them to uninstall them.

Twitter does something shady to get a list of the installed apps on the device.

The link is 6 years old and the direct link at the bottom mentions (like I) that that particular method is not viable anymore.

As for the 'check running apps'. Maybe that works still, but as mentioned it only works if the apps are running at the same time, or recently. So it would never give you a full list.
