Performative cynicism + speaking hypothetically about past events = I'd downvote it twice if I could. In reality very very few ISPs are giving one IPv6 address per customer. ISPs are greedy but they're not wantonly cruel.

In actual reality, global IPv6 adoption is at ~33% [0, 1], so I'd say this is, at best, a premature and naive presumption. ISPs actively engage in rent-seeking, and resource scarcity is another contributing factor. In-short, there's nothing in OPs comment that warrants the downvotes.
