Yep. If someone is trying to make you do something, or stop doing something, or buy something, your first question should always be "Why?".

Why would someone try to force me off of my browser (that has ad-blocking and tracker-blocking mitigations) and on to a locked-down app that may want permission to run in the background, display notifications, access my files or camera, etc?

Maybe it really is to "improve my experience"... yeah, right.
