He's charging $50 for a $21 unit
So? Before this blew up I had no idea this thing was available, and even now I do I'm not sure I want to try and buy one-off on alithingy. $30 for knowing it's what I want, where to get it, and then getting it for me seems fair enough.
Of course, YMMV but then if you don't think the sums add up you can go and get your own if you want one. No-one is stopping you. You can even offer one to me for a $25 mark up, but it's too much hassle for you.
You should see the reddit AMA
Don't need to. I know he is lying and this is a scam. You make the mistake that because I called you on the frivolous justification you used, you think I am all for this kickstarter, but the reality is that I am not. I called you because a) this is a common point people bring up when they are erroneously outraged, and b) it hides and spoils grievances that are valid.
Instead of whining on about someone else making a buck, point out that this cannot be the open source he said it is. That should be enough to put the kibosh on it by itself.
