Your understanding of Net Neutrality is largely wrong, and your understanding of what happened vis-a-vis AT&T/California is also wrong. AT&T are absolutely allowed to bundle HBO Max within plans in California (and do in fact). What they're NOT allowed to do, as an ISP, is treat one downstream provider differently in terms of internet throughput/caps/access/etc. AT&T imposes data caps on all traffic, but then tried to make HBO Max not count towards the data caps like competing streaming services are. This was AT&T using their ISP position via data caps to give their other service an unfair competitive advantage which is unlawful in terms of net neutrality. California rightly squished this. The Amazon question is predicated on something that never happened (i.e. that AT&T were told to stop bundling HBO Max with phone service), rather than what actually happened (i.e. AT&T were told to treat HBO Max and competitors equally for data cap calculations). Since it never happened, the Amazon Prime question in turn doesn't make sense and NN has nothing to do with bundling.
