No silent downgrade
You've felt the downgrade already, even if no one told you. Hit a usage limit on a frontier model and most providers quietly switch you to a cheaper one without asking — it's documented, standard behavior, not a rumor. You keep paying, you keep typing, and the model actually answering you is no longer the one you signed up for.
