I get what you are saying about it being easier to move from one walled garden to another (based on the evidence that those moves happen more often than moves from between email providers)... but there is such a huge caveat that those moves are never a move chosen by an individual.<p>I cannot, as an individual, choose to move from one walled garden messenger app to another - if I do, I cannot message those people that don&#x27;t. I am stuck going along with the group. This is ok in a lot cases (when the group&#x27;s priorities line up with mine), but sometimes the things that are important to the group are different than the things that are important to me. For example, I might prioritize security over ease of use, but since the group doesn&#x27;t, I will never get my wish, and I am stuck on a service that sacrifices security for ease of use.
