For context - he has a ~9m sub youtube channel on phones that must be banking it. This is a side project that appears to be grown out of frustration of disabled wife & seeing the shitshow that wheelchair market is. Seems 10/10 wholesome to have this disrupted by someone that cares
While it is absolutely true that he cares, I think you are selling his long term plans short. The primary growth factor for the channel was reviewing phones with the repairability / endurance focus, but somewhat recently he expanded to topics such as plugging abandoned oil wells which are leaking methane and wheelchair mobility issues. From what I understand he has a couple similar things in the pipeline.
