Nope… They’ll be left with unused IPv4 addresses which is not a significant source of income and they’ll be able to significantly reduce the costs incurred
in supporting things like CGNAT.

Probably they will sell it to business customers instead of the residential customers. However, we’re talking about relatively large numbers of customers
for relatively small numbers of IPv4 addresses that aren’t producing revenue directly at this time anyway.

About 2.5 years at that price since a brand new home router is about $29.
