Because AMD has a tiny market share. Trust me, if AMD would be on top, it would be riddled with holes, just like Intel

  It's true. I've read one side channel attack paper that admitted towards the end that the researchers didn't actually even have access to AMD hardware to test with, but thought it should work in principle. Fact is Intel takes the brunt of these attacks because their HW is more available especially in semi-standardised environments like universities. Also, Intel fund researchers (this paper was part funded by Intel), and their technical documentation is better than AMDs, at least in my experience. That makes it easier to understand the CPU internals, which is a big part of these papers.

  In the server market Intel had 92.9% for Q4 2020. AMD is actually up a lot in that market, Intel had 95.5% in 2019, but outside of a few specific use cases Intel still owns the market most likely to contain interesting information an attacker might want. This attack as it stands does not seem to apply to Intel server hardware from Skylake to present due to a different interconnect architecture, though the researchers indicate a belief the attack may be portable it would also be more limited. Complete rectal estimation here, but I'd imagine executive laptops to probably be the next juiciest target as the end user station most likely to contain "interesting" data. While AMD has been making incredible inroads in the laptop market with Zen 2 and especially Zen 3, as opposed to the Bulldozer era when seeing an AMD sticker on a laptop let you know it was the cheapest one on the shelf, they still haven't made it to the models commonly bought by businesses. AMD is absolutely killing it in the DIY desktop space, deservedly so (this post typed from a 3900X that I love), but on the OEM side of things you still generally have to go out of your way to find them in anything not marketed at gamers.
