I urge you to ask anyone who provides technical support to the elderly or tech inept what the split is iOS to Android RE scams,
malware etc. Nobody's arguing the app store is perfect, but "the exact same problems" is absolutely an incorrect statement.
To me, for the problem to be "exactly" the same, it would need to occur at a similar level. I do not believe (based on my personal or professional experience) that this is occuring at a similar level on iOS or Android.
You're right the same specific style of problem happens at both, but if it's significantly more on one than the other then it's hard to honestly say they're the same.
