Question about MAC sharers

[Soma]

Okay so, we've all seen these MAC's doing there rounds on social media, and it's causing a problem with server load. My question is though - Why can so many different people use one MAC address? I thought the system only let's you stream to one device per MAC? (If you try to stream to 2 separate devices, it comes up with a error I heard). Are these special MAC's that don't have device limits or something? Thanks!
