Nvidia has provided the same API incrementally extending it since 2007. And supported it on most of their GPUS including consumer cards. Oldest cards supported by the latest version of their SDK were made in ~2013-2016. See table in https://en.wikipedia.org/wiki/CUDA#GPUs_supported
AMD has been a lot less consistent with their support changing their mind almost every 3 years. ROCm was initially released in 2016 (that's 9 years of headstart for NVIDIA). If you look at https://docs.amd.com/en/latest/release/gpu_os_support.html on Linux only the enterprise server cards are supported. Situation slightly different on windows https://docs.amd.com/en/latest/release/windows_support.html where they support last 2 generations of consumer cards (partially). I remember there were also a few years with even more bizarre situation where they supported GPUs that are couple of generations old but not their latest cards.
Not hard to see how developers are hesitant to spend time adding support for AMD if large portion of AMD users won't be able to use it and there is a high chance that after few years AMD will change their mind again coming out with new API or dropping support for cards that are only couple of years old.
