Right? "This platform does/does not run my software" is a huge checkbox when buying computers. The viewpoint of people who actually specify, buy, and operate servers at scale is severely underrepresented in these discussions.
Keep in mind that Intel also has to compete with AMD... and AMD is also x86_64.
AMD and Altra are trading blows at the high end of performance, as seen in this article, while Intel is... not, except in extremely specialized applications.
Intel servers don't even offer PCIe 4.0 at this time, which is just a bad joke when it comes to building out servers with lots of high performance storage and networking. For now, Intel offers (relatively) poor CPU performance and poor peripheral performance.
So, if your software can't run on Altra, the other choice for high performing servers is AMD, not Intel, unless you're just locked into Intel for historical reasons.
Intel does have some nice budget offerings for cheap servers, though, such as Xeon D.
I don't know if it's a mistake, the competition is welcome. I spun up some arm servers because they were lower cost but then ended up having to worry about software availability issues. It's non-trivial and I don't think it was worth the savings at this time and went back to x86.
Regardless, the claim that there is no value in Intel let alone x86 is a stretch.
