Nobody "attaches" the profit motive--it is inherent. Nobody spends millions of dollars on research and dedicates years of their lives to it for free. They either do it because the government is bankrolling the endeavor (like much medical research), or because their is a potential for profit. I'm fully willing to entertain the idea that the government should be funding all this research that would otherwise be done by private industry, but someone has to pay for the R&D.
