I'd hope anyone who saw "Plane Crazy" would know better than to back a Robert X. Cringely Kickstarter, and I'd expect anyone who followed his tech takes for a bit would have acquired some salt to take with any claims he made.
There seem(ed) to be a number of folks absolutely obsessed with hounding Cringely (apparently dead, I know) over the Kickstarter in his irregular posts. Given the highest tier was $200 and the whole of the Kickstarter was $35.5k USD, seems like a lot of throwing good time/energy after a bad Kickstarter call. I'd be overjoyed if that was the worst case of someone walking off with my money I'd ever faced.
They are, or were I guess, free to do so, but it seems wasteful to spend the amount of time in his comments they did.
