Why does my toilet paper need a website?

I looked at the package of toilet paper I recently purchased, and on the back it lists website information. Does anyone else think that’s a little weird? I understand needing to know if it’s safe for septic systems or an RV, but that information is on the back of the package as well. I think everything you might want or need to know is on the package. True or false? Not everyone or everything needs a website.
