I doubt a big company would draw the line in the sand. But I could see an upstart (think TikTok) not having up enough IP addresses and just giving a crappy, slow proxied experience over IPv4, but having it be native, zippy and good over IPv6. Suddenly you have teens begging their parents to switch ISPs.

That comes with a major assumption that switching ISPs is an option. Most people get to choose between their cable company, or a fleet of ill-trained pigeons

As an example, the options where I am right now (thankfully temporary) are:

- $55/mo. 3 Mbps DSL

- $80/mo. 300 Mbps cable (or even more expensive, faster cable)

- $120/mo. 100+ Mbps (if you're lucky) Starlink

- A few other heavily restricted, very expensive satellite options (e.g. HughesNet), to which the aforementioned fleet of ill-trained carrier pigeons might be preferable

Only one of those is practical and (mostly) reliable for anything remotely approaching something like remote work.

Back home it's such a luxury to be able to choose DSL, cable, or fiber. I can only dream that all markets will have an actual choice between Internet service providers someday.

Did you look at doing 5g home Internet? There's great coverage in lots of areas.

At least in Canada 5g comes with $50-for-15GB levels of data cap pricing

Actually most people (in the US) get a choice between the cable company, the LEC, and a 5g carrier, and maybe even StarLink.

I have a choice between the cable company and sorta Starlink (Starlink isn't actually available in my area yet, and is a nonstarter anyway). There are no other options available to me.

Many of the "choices" are false choices. My home, in the downtown of a major city, shows as having two choices for wired broadband, but the phone company's wired broadband option is an old ISDN network grandfathered in to "broadband" that probably shouldn't have been, it is the very bare minimum of "broadband" in 1990s standards. (And the phone company charges the same monthly cost for it as actual high speed broadband options they provide, just to add additional cruelty.)

I think you'll be surprised. As soon as most large and medium businesses support IPv6 we'll start to see people dropping v4, likely within the next 5-10 years. When only a tiny % of your potential customer base is dependent on v4 you start to weight the cost of staying dual stack or just going pure v6

That was the work of a few people on the YouTube team, not the company itself taking a stand:
