"Is it impossible to keep malware out of an app store or an extension store? Perhaps, but Apple has come close to pulling it off — the number of known incidents involving malicious apps found in the iOS App Store over the past decade has not yet reached double digits."
And that's not even a complete list.
Apple forbids and even legally threatens Security researchers from publicly disclosing what they consider to be harmful security exploits.
Not to mention, 9 out of 10 smartphones used globally are Android phones. It goes without saying, therefore, that 9 out 10 malicious software targets Android.
What's even more impressive that even though 99% of malware targets Android less than 1% successfully evades Androids built-in security.
So your theory that Android is riddled with malware is backed up by old wives tales. It is objectively and factually false. But I understand you have a narrative to follow and clicks to earn.
