I really don't feel like I have much vested in it at all, it hardly takes up any time at all. It's not exactly difficult to click eggs.
The owner of the site isn't charging people, so I don't see any 'exploitation' going on. If the guy makes money from ads (and I doubt a site like this makes very much), then good for him. He designed something that some people seem to enjoy, and offers it for free, so what's wrong with putting up a few ads? Oh noez, making a profit (if he is) is evil!
Calling it 'supremely stupid' is dissing the 'players' (such as they are), not the owners. If it makes money, then it's hardly stupid of the owner.
Some people would consider Igiss 'supremely stupid' for putting so much effort into a mod for an ancient computer game and not even getting anything out of it.
