The way I think others are thinking about it is that to Activision, making innovative new franchises or long term investments in general is a big risk since they are 100% a games company. Whereas if Microsoft owns them may face less pressure to cut costs/long term investments since it would make up a much smaller part of Microsoft's financials.
Whether that is how things usually turn out in practice with these sorts of acquisitions is a question I don't have a good answer to.
