Actually not the case -- the TB chipsets are from Intel and promoted by them.
TB drives are pretty fast and great to use if you can afford them. TB external GPUs are useful for ML too (not sure if anyone is using them for actual rendering; that's outside my field of experience).
To an extent - many laptops and nearly all desktops don't have Thunderbolt at all. TB external GPUs are probably the main use-case for the technology today (people indeed do use them for rendering)
