Nice, they will be released, so the blocks can be bought by AWS, etc extractring rents for a long time ... Why don't we switch to ipv6.

They won’t be released, because releasing them would literally wreak havoc on the IPv4 internet. Releasing them could be the best thing for IPv6 to ever happen.

Because of IoT - devices are inherently insecure and they are currently obscured by NAT. Imagine if billions of printers, weather stations, baby monitors, toothbrushes and thermostats suddenly obtain publicly routeable address...

  Consumer routers typically have a firewall. Additionally all those IoT devices are able to obtain these publicly routable ipv6 addresses already in millions of homes, its just the numbers are lower

  The main issue is that you can port scan all those IPv4 addresses in minutes. It's impossible for v6 so the issue, even without a firewall, isn't a big issue. I know you can do address harvesting like it was done with pool.ntp.org by shodan but if you don't use any public services your IoT devices are basically protected by the 128bit address space. So you need a address harvesting possibility, and people are watching for this as seen in the shodan case, and an exploitable issue at the same time. Not impossible and you should use a firewall but orders of magnitude less scary than a public routable IPv4 address.

  That's what link-local addresses are good for.

The most likely thing to happen is nothing. Next most likely is they are re-classed for private usage. If they are re-assigned for use on the internet they will be assigned to the RIRs and distributed under their policies. No no way AWS are gonna be able to hoover them up like they can when acquiring space from existing holders.

If they get reclassified the RIRs will likely have strict allocation policies for them and only hand them out to new operators.
