The answer to this is in two parts. Firstly, you need to know just how deeply RED and ONE's billionaire sponsors are invested in the DAPL. The new addition is that now you'll learn that Warren Buffett not only has majority control of the corporation with a 25% stake in the Dakota Access Pipeline at over $6.3 billion (it's decreasing), he also has majority control of one of the most egregious banks invested in the DAPL, -at over $28 billion.
This page also tells you how much Gates Foundation is financially dependent on Buffett. It's enough that it makes them proportionately invested in the Dakota Access Pipeline staked corporation around $1.6 billion, which is about three times as much as any of the maximally invested, subject to international boycott banks.
Here's another worthwhile #askU2 Question that was discovered post hence: Were you aware the current Governor of North Dakota not only received more than a $100,000 from oil companies but also received $106,000 from your ONE/RED sponsor, Bill Gates, and was previously the chief of staff for Microsoft in Fargo?
