There is a lot of abandonware out there that limps along. Most applicable is all the semi-failed social media: MySpace, Digg, LiveJournal, Foursquare, etc. are all still out there. Maybe they have problems with illegal unmoderated content and bad uptime, but nobody cares. Some still make money. I doubt any, maybe all of them put together, are worth 10% of what Elon paid for Twitter.
