All George is really asking for is AMD to entirely reorient their business, change their sales and marketing strategy, hire in a cadre of extremely expensive software engineers and give up the entire margin they make on the chips. No big deal.
It's like... sure, it'd be great if they were suddenly a fantastic new company that operates differently, but we live in the real world here.
* tiger teams or specialist troubleshooters and project pushers are almost certainly already a thing in AMD
* their "this shit is on fire assign it to a tiger team" criteria may have absolutely nothing to do with Geohot's complaints. things like legal or compliance issues, Taiwan getting attacked by China, high rates of turnover on [specific team], or a problematic design may rank a lot higher than some rando who got headlines a few years back for some good cracks.
And it's not because the problem is "that hard", it's because AMD doesn't have many skilled engineers like you mentioned at the end of your post (basically contradicting yourself!), and won't prioritize the right issues.
