It's a bit of a strech to base that reaction on that article. It defies my expriance. I keep my C41 alive for at least 6 months in these containers. I could go longer if I controlled the temp in that room (non ac).

I am not going to deny a marginal amout of oxygen will get in, but not an amount that will serriously affect the task at hand. You will get more oxygen polution from opening up the bottle to use the contents. You would still have to do that with glass.
