The thing is they will start to see big headlines in the coming months, lawsuits, some big name company jumping ship from Intel to AMD, stock dropping. So headlines of how "good guy Intel provides support for older platforms and saves users money" are the kinds of headlines they might be desperate for in the coming months.
I'm not sure they are smart enough to do that, as everything about this has been about saying our bad, but we're putting everything we have into fixing everything we can, they kinda went, yeah but everyone else is as bad as us only for every single site out there to call Intel idiots and point out that AMD, ARM and probably Apple are no where near as badly effected as they are.
