This is the pathology of large business executives - once you have a mature business, it is boring, and pretty much anything else seems exciting, and so you focus on this new thing, and worse, start promoting it internally as a model for everything _that's actually successful_.
Due to my career wanderings, I've seen this a few times, and many times the hot new thing has been a mountain of technical debt that has spent the last few years doing everything possible to juice growth and spinning amazing stories to investors, the press, etc. They've been selected for telling a great story. The executives at OldCorp tend to have a natural immunity to the messaging and scheming of their interior ecosystem, but they are not used to these invasive species.
If this is what Gates is getting at, I think that's very astute of him.
Which is a shame, but the corporate game theory optimality of leapfrogging between hot projects has held true at essentially every company I've ever worked for.
I'm talking about something completely different - the executives in this case are not knowing participants, they are in the state of mind to be snowed.
So whether it's an external acquisition or internal project is somewhat immaterial.
