It’s not “downright dishonest” to point out that the EU previously shared the unquestionably true fact that third party stores and sideloading are much riskier for end users. Just because it’s not on their website anymore doesn’t mean it’s not true (especially because, again, it literally is). It’s even possible the EC got it pulled after Apple quoted it because they realized it made them look bad.
ENISA also
says:
“Compared to other software distribution models and depending on the review process implemented,
the walled-garden approach makes it more difficult for cyber attackers to spread malware" and that "most experts agree that the walled-garden approach could help to reduce the impact of malware."
But want something still live on the web? Here you go. The European Agency for Law Enforcement Cooperation
says: "only install apps from official stores".
It said “
Use the official application marketplace only.” It was about Android malware that “requires users to manually install a malicious application outside Google's official application marketplace”. So yes, it didn’t say “App Store”, but come on.
