I notice that Skype is listed as end to end encrypted, though it is 
apparent that every skype interaction is scanned for content.

Skype suffers undue delays, because packets are not sent end to end, but 
through a center or small number of centers, which became grossly 
overloaded when large numbers of people started to work at home.

According to 

	Skype doesn’t use end-to-end encryption at all. That means every 
message, call, and file can be viewed by Microsoft.

	Voice, video, text, and files sent between Skype users are encrypted, 
but only between your device and Microsoft’s servers. That data is 
decrypted once it reaches the server, allowing Microsoft to snoop if it 
so pleases.

I therefore, knowing Skype to be insecure, did not bother scanning the 
rest of their recommendations.
