Why change something that works?
Users don't care, and until a lot of them do ISPs won't do anything.
People can still video chat, play games and use VPNs without v6.

Part of why video chat quality sucks is because the RTP traffic has to be sent through a proxy to deal with NAT, doubling load on the Internet and increasing latency.
Because it does not work.
Want to run a public service with end-to-end connectivity? Go to your RIR to request an IPv4 block and be put on a waiting list.
Or break out your cheque book and be prepared to cough up $35+/IP for the privilege of global connectivity:

When I signed up for a new data center internet connection, both my ISPs charged me something like $25/month for a /24.
IPv4 addresses are still relatively cheap to get.
When did the company purchase them? Was it a private sale or through a broker(?)? I'm curious as to the process, especially if it was more recent.
But maybe IPv6 is so low level that it has a lot more inertia...
We have run out of IPv4 addresses. Past tense. Go to a RIR for some and you'll be put on a waiting list.
If you want a block of IPv4 space you'll be paying about US$ 30 per IP at the moment.
