I had a response from BBTS.

Hello <Zommael>,
Thank you for the information and I will be sure to explore this further with the appropriate department(s). At this time we are still shipping Hasbro products accordingly and you need not be too concerned. If there are further restrictions our website listing(s) will surely be updated accordingly.

So basically it's just a rumour, they're looking into it, and don't panic. Not quite the "Hah! I'd like to see 'em try!" I was hoping for, but also not a confirmation that it's going to happen any time soon.

I'd suggest this has more to do with the Italian postal service than Hasbro at the moment.
