Hi Brian,
It was to be expected. Power corrupts. Control is power.
Elimination of viable competition means ultimate control.
Microsoft knows this very well. Apple, Facebook and Google know this too.
I fully expect to find CDbaby owned by Sony or Viacom in the not too distant future. Then I figure the doors to distribution will be slammed closed once again. The old class structure was the rich land owners in a fortified castle and the rest working hard all their lives with little to show for it.
The folks at the top want to keep it that way and the standard method is to either kill or welcome the new power brokers into the fold. Then teach them the rules of power as you pull up the drawbridge.
