MPEG-LA and HEVC Advance patent pools expected companies like apple and Microsoft to pay for it. In some cases orders of magnitude more expensive than H.264.

H.265 licensing has historically been extremely expensive. This becomes cheaper, because the license was paid for by the chip company. But the result is the same as having browser support. It is offloading decoding to the OS (Windows), and the OS is offloading to the hardware. In this case, the browser still does not support it. I updated the question because there are reports of it working in Edge when hardware decoding is available. And wide support is not likely to be added in the near future.
