I don't think that they will ever change their mind to favor Bitcoin. After watching the whole video I haven't found anything regarding promotion or support of Bitcoin mining. It was basically showing that how can we transfer that renewable energy that comes from wastes into energy that we can use to run data centers.
Their initiative is a positive step for data centers but I don't think that WEF will ever promote any firms that are going to favor Bitcoin or its mining. Their mindset won't allow them to accept the mining as a possible way to utilize wasted energy into something as good as Bitcoin.
