There's a slight risk though with buying in that you didn't mention...the risk of taking the platform exclusively as a business.
Other than that I agree with your perspective on buying in and how it actually changes a lot of POVs to the good of the platform
What I have found from most people is that they don't tend to do that but rather get emotionally involved with the business side of it too. They usually start learning more widely and seeing connections they hadn't before.
