I don't see how this is seriously a suggestion. Not everyone lives in Silicon Valley and earns a >20k/yr paycheck. There are other things to consider like reliability, cost, that force your hand.

Anyway ISP that blocks port 80 or uses CGNAT is obviously not good a selection for such a user. So it's serious suggestion if you can choose ISP. There are many places where can choose ISP even not in SV (maybe outside US).

What else do you want? If your ISP blocks incoming connections then thats the end of the story. The answer is either complex things like tor or switching ISP.
