There's no way to stop it in the current system we've got, and as mentioned the issue has spread from commercial labs to the university sector. For me it boils down to money. All my research funding is from governments, and they typically aren't interested in any sort of direct financial windfall. If I was privately funded by someone with an agenda, say proving that supersymmetry exists in my case, then I can see pressure for my results to point in that direction. There are very strong checks and balances which would stop that from happening in my case, but other fields of science have different standards of proof.
