Neither Tesla nor SpaceX rely on millions of fickle web users handing over their personal information and regularly signing in to a website to look at photos and status updates. Nor can they be easily replicated by a competitor who is not a jackass.
I see. You get to baldly assert that SpaceX and Tesla are hard to copy, though few have yet tried, but when I point out that people have tried and failed to beat Facebook at their game, these things take time?
