Bobby Kotick insults every indie game dev in the world (Except Bungie)

[Proton]

Actually "indie" is a term made up by people

Indie is just a short form of independent.

in·die   
[in-dee]
Informal .
–noun
1.
an independently owned business: to work for an indie.


IE. Any video company not owned by a publisher.
The publishers are,(in the case of video games) Sony, Microsoft and Nintendo.
So Bungie was Microsoft's bitch, but they've moved on.
Halo is over.
Bungie left Microsoft to become indie studio.


Activision makes games for every publisher, so they are an independently owned business that is headed by Kotick.
