I'm not sure I follow your logic. Paying for a service does not mean you get access to all potential services a provider offers. Providers can choose to keep some services internal.

Silly example: I pay Netflix for their most basic plan, so I get ads. Just because I already pay them money, doesn't mean I have a right to no ads! It also doesn't mean I have a right to 8k streaming; maybe Netflix reserves that for their internal cinema.

Both companies offer "MAX" or "PRO" plans - and the best models were available to those customers. This new wave of "It's too dangerous for the public" is a new initiative from both companies.

I agree with your overall sentiment. Paying for "Claude Mini" doesn't get you "Claude Maximos".

However, the overall precedent that the companies have set is that if you pay for the top tier subscription, you get the top tier model. That's not true any more.

You have the right to complain and ask for more though

When Netflix launched, you got the service without ads. That has changed. That's what's known as a rug-pull.
