Paid grids don't work.

What we are doing here is charitable - humanitarian research freely given and publicly available.

Paid grids do less desirable work, but still can't afford to pay what your computer time is actually worth. A supercomputer or purpose-built grid works out much cheaper, if you have the money to pay for it.

Projects that run on WCG don't have the money to pay for supercomputers, typically. Instead, they rely on our donations, and the computer time we give would otherwise be wasted. So everybody wins.
