The whole thing is based on Gridcoin and BOINC anyway, so the good thing that comes out of it is that BOINC research projects like Rosetta@home get more computing power for free.

For this the suchflex guys earn Gridcoins, which they can sell directly on the market and convert to money. But a user could leave out the middleman alltogether and just mine Gridcoins (or alternatively other cryptocurrency but for that you need ASICS) themselves.
