Ahhh no not at all.
First and foremost Activision didn't own Bungie, Bungie had complete control over their games and what into them. A lot of the MTX and especially Everspace was an idea from and added by Bungie themselves which they have admitted to (

They could not continuously meet the deadlines they agreed to with Activision for the release of DLC, and everspace was their way of trying to drip feed content so more time could be spent on bigger DLC packs. Mostly due to their pool dev tools if i recall.
As for the cutting of the content from D1 and D2, you just need to look at Bungies history to see that this is a common occurrence with them. D1 and D2 both got complete reboots around just over a year out from release at the behest of Bungie management (

Bungie butted heads with MS, and butted heads with Activision who is the common party in this so far?
Not saying that Activision is a saint and faultless in a lot of ways. But in the case of Bungie, they don't exactly have the best history of management behind the curtains at all. But to say everything wrong with the Destiny series is because of Activision is out right wrong.
