Chia didn’t sponsor Max, it bought the tech (haven’t seen the agreement but thats what I think) which is different.
Small clarification, without any asking from him, we gifted him a 5 figure sum of money, no strings attached, as a thank you for his contributions and in recognition of his development work, when we opted to include Madmax Plotter in our base install around the end of 2021. So yes, we did sponsor his original plotter.
