So, its a long game - make it generally irritating for people to use other services. Every time they introduce a feature, make it opaque and difficult to implement. Other services, other MUA's have a hard time keeping up. The users get frustrated that things dont work: "I don't get these stupid emails in Outlook" "LibreOffice doesn't display my document the same" "Firefox doesn't show the page properly" => "Can we just use Outlook/Word/Edge"

Is that the case here? It sounds from my limited understanding like this is not difficult to implement and is even easier to turn off.

I understand the EEE model and the concerns with it. I just don’t think this fits that model. This is just a feature.
