Yeah fair, I'm one one today. I genuinely thought this was a joke at first. But you're right, I should just put my money where my mouth is and make a github pages or similar that replicates this functionality as something that you can download and keep forever, how hard can it be?

It's utterly disgraceful to charge money for something like this as a service, but that doesn't excuse my conduct in response. The implications of validating this sort of rent collecting are insidious and serve. We really need to re-evaluate what our definition of 'value' is as a society.
