And yet it is absolutely not true, and again, isn't true for literally all major carriers into he US. Congratulations you haven't noticed it. You're either lucky and simply haven't experienced it because where you live isn't congested enough (even at an event). Or you're simply not noticing it.

I don't know the full details of your plan, nor do I know what they're offering you. The new plans might be worse than you realize for many reasons. Hard to say.

You can keep saying you're not being deprioritized until you're blue in the face, doesn't change the fact that you absolutely are. Because again, no major carrier doesn't do it anymore. It's across the board for everyone. Period.
