It is good press at a time when AMD is very visibly looking like they lost out on the first round of AI. His project is open source, AMD likes that and can benefit from the free developer feedback. I'd say this is less about George and more about Lisa being the insanely smart and talented business person that she is.
He emailed her after he had his meltdown. It wasn't like she saw the meltdown and wrote to him. He is nowhere on her radar.
By the way, I also got a bug in the AMD drivers fixed too [0]. That bug fix enabled me to fully automate the performance tuning of 150,000 AMD gpus that I was managing. This is something nobody else had done before, it was impossible to do without this bug fix. We were doing this by hand before! The only bummer was that I had to upgrade the kernel on 12k+ systems... that took a while.
I went through the proper channels and they fixed it in a week, no need for a public meltdown or email to Lisa crying for help.
