I think you misunderstood something here. They are buying back tokens which they will then put in a fund that is meant to be distributed to DApp developers as incentives for their developing work. They are not planning to raise new funds as of now.
Ah, I didn't know that yet. Paying developers with their own tokens is of course a good idea. But you also have to find developers who are convinced of the project and want to take the risk of a price loss.
