Some people seem determined to make other people's choices for them.
You threaten to sue Foma. Isn't it easier for you to just make your choice to not buy their film?
In the end, your suit would fail because you are not qualified to determine the expiration or best-used-by date for this film. Each producer is free to make those determinations.
I will order 10 rolls of Foma today to display my support.
