The thing is, there are just as many /28 IPv6 ranges as /28 IPv4 ranges. And the experience with IPv4 is that it's those larger ranges that we've run out of the quickest. The whole power of IPv6 is that assigning a huge global business a /32 gives them enough addresses to run more devices that exist on the whole Internet today. But if we're distributing large swaths of IPv6, we'll run out just the same, unless we try to later claw them back like we did with some IPv4 /8 spaces.
Now, of course, a /28 in IPv4 is a tiny range, while a /28 in IPv6 is huge. And there are, of course, a lot of /28s. The fear is only that we may start seeing larger and larger allocations for no good reason whatsoever. Apparently already some random private company (Capital One) has received a /16 IPv6 range - this is an absurd allocation that should simply not be allowed if we don't want to have to move to a new IP version in a few decades.
