Unfortunately this is true. I've been running IPv4/IPv6 dual stack since 2014 for most of my infrastructure and since 2016 for all of it. The company I work for now is a major AWS customer, and we managed to pressure them into enabling IPv6 for Global Accelerator, and have just recently launched full IPv4/IPv6 dual stack for our endpoints... in 2022. I think that the primary root cause of this is economics, if we're being perfectly blunt. The countries/regions of the world that got most of the IPv4 address space are also the places where most of the money is, so businesses, especially businesses serving businesses, are not heavily driven to support IPv6 other than as a "checkbox", because their customers all have IPv4 and are not asking for it. Meanwhile in APJC/BRIC IPv6 is the dominant mode of connectivity, and many major businesses are IPv6 only or IPv6 primary w/ IPv4 CGNAT. When you enter into this market, IPv6 quickly becomes a requirement, however in EU/NA, it's just not required. I am seeing this shift though, because of mobile-first consumer-oriented businesses. Globally, pretty much all mobile providers issue only IPv6 addresses that are globally routed to their subscriber devices and utilize CGNAT to get IPv4 connectivity. This is true even in North America. The problem is that CGNAT is /really/ good as far as "working", so from the perspective of endpoints they communicate with, it may not be obvious that IPv6 would actually benefit them. For mobile applications, IPv6 has a significant performance advantage because it skips CGNAT, and so at least in that space businesses are doing more to support it directly.
