Probably, yes. And that's why we have situations where games are just abandoned. I'm willing to bet games like MGI wouldn't have ended the way they did if instead of ending up with a ton of money for little to no effort, the profits would have tapered off after reaching a certain level, slowed down if the author didn't post anything for a month.
I didn't pay a cent, so I can't complain as much as someone who actually invested hoping for a good game, but I think these are examples where "why do you care what others do with their money" doesn't float. Because some people just don't care and pay the devs for nothing, more people get robbed of a potentially good game. Everyone except the devs, or arguably even the dev, loses.
