This is interesting. In full disclosure I work at AMD, so I was genuinely interested in your point of view. I am generally less informed on the consumer side of things, both as an employee and the fact I'm not a gamer or a DIY home PC builder. So I'll take your POV on AM5 and all things Client at face value.
On the server side, I've seen some shit. I absolutely don't think we've made 100% perfect decisions, but I also absolutely know people underestimate the influence Intel has on customers and the ecosystem, even years after our obvious dominance on the technology side. Our CEO made a major announcement at a event in the last 3 years regarding support from a major enterprise ecosystem partner, one that was not done on a whim and was supported by quotes by the company expressing their support, and the next week that support disappeared. We have enough insiders at this ecosystem partners to know we had met every demand for support and payment they asked for, and after the fact Intel came in with enough zeros on a check to cancel everything.
I've heard enough stories from former Intel employees now at AMD to know they are fucking dirty, threatening to withold marketing payments companies rely on to stay afloat. Or friends at Dell that were told their intel spiffs werent valid unless they maintained 90% share for Intel. So when you say its about "you selling their shit for them", what I've witnessed is customers saying flat out, "I'm not selling your product unless you pay me to". It has nothing to do with proposing the best solution for customers. Even with that headwind, we're at 30% market share in server.
Regarding the comment of Global Foundries, that was one of the few good things from the Hector regime. It was a "stop digging and drop the shovel" moment. And it's proven to be the right move, so not sure how that ends up in a list on how AMD has been mismanaged.
In an all-timer, Hector drove his Ferrari to the office on the day he announced laying off 10% of the company.
