That's not how the economics of it work, some people who discover SC absolutely ##### love it, perhaps for every 10 people who discover SC 1 loves it.
Even bad publicity is still publicity, it all draws attention to the subject, bad publicity can still make people with money to burn curious, and they might actually like it, some do. If anything some of the more extreme publicity can help it, they might expect i to be completely unplayable all the time, and often its very playable, so they have a better experience than they expected.
SC has a real appeal to enough people, despite all of its problems, that's why it keeps going and going for so long now that others have come and faded while its still going strong.
