The things like Philippe is doing are being done by many companies too.
Being living in Toronto area, I happen to know about a researcher in Toronto
University who found a drug of a company harmful through her research. The
company was threating to sue the researcher if she didn't stop the research.
Interesting is that the research project was financed by the company self.
Competition and money-making don't allow people have time to take ethical
quetions into consideration. The worse is yet to come since the ongoing
globalization of the capitalism will further diminish the regulations of the
states over businesses.
