Because that perception is wrong. Based on poor judgement (often Youtube clickbait and low information Reddit), based on simply a lack of knowledge regarding CPU architecture.
I would not upgrade yet from this 11900K because it's the best homogeneous core design that Intel released for desktops. It includes AVX512, and is the only consumer CPU from Intel to have it. Intel engineers have stated that they are dedicated to furthering AVX512, and that it's removal is temporary. All of the errata from Skylake was finally fixed in Rocket Lake, which went on for generations until Rocket Lake.
Some people were so deadset against 11th gen that they recommended 10th gen because there were 10-core CPUs. Yet the ringbus design it inherited from Skylake was very strung out by that point with unresolvable issues like the well-known L0 parity error. There's many other reasons but I doubt you're interested in rehashing Rocket Lake as it sounds like you feel you have enough information to make up your mind.
And I certainly wouldn't use AMD due to even more bugs than Skylake and poor latency. They're improving, but it's not my choice.
