Both companies are valued in the billions, and it certainly seems like a response to the lack of Tether's transparency.
Ultimately this is a good thing in my opinion
This is a big step to a stable and transparent project. This way, more people will be confident if there is a stable one. In time of volatility, there is a true /transparent/ reliable stable coin which investor can park. With the two big company partnering for the project, this is a good start.
