This happens quite often. If you have an analog TV and DTV is deployed, at some point you can't use anymore the analog TV unless you "add" a "converter". This was done with the government mandate. I recall a Spanish operator that was asking the customers of old "rotary-dial phones" to move to DTMF ones. Customers that don't want to do that, either buy an expensive "adapter" or get their contract canceled, instead of renewed. This needed the government mandate. I'm sure this happened in many countries, and the "mandate" have a very specific plan, with timing for every phase, such as "no more manufacturing in the country allowed", "no more importing to the country allowed", "no more sales of old stocks allowed". I perfectly see that at some point, operators can choose to do the same with IPv4: you get a converter (an RFC8585 compatible router) from the operator or from the retail store, or your contract is not renovated. This is perfectly valid also if at some point governments in their duty to protect consumers, take the necessary steps.

Or do users *opt* not to buy such phones for a reason? (there might be an implicit message in the possible answer to this question).
