Does that mean we should all thank Twitter for creating this scarcity so we can charge more for our products?
There's nothing to feel sorry over in this case. These guys were blessed (non-denominationally, of course) with a product that people want, and aren't able to capture the value in it. That's what running a business is all about. The product is only one (albeit large) component.
And this isn't irreparable. If too many customers breaks you, you're in the wrong business.
