no one should need to explain the difference between BH hosting a free livestream of old concert dvds (in order to sell tour merch) and SM charging to stream new live concerts for groups, most of which have zero officially recorded concerts online.
they all want your money, guys.

i watched Bang Bang Con! I'm gonna watch some of these SM concerts! i've also watched a ton of old EXO concerts recently, because they're all online for free! do what you want!
