Fair points, although probably more to do with semantics than principle. The bottom line is that these products have been in service for years, over which time a significant amount of potentially very dangerous failures have been well documented in the public domain (and presumably this coverage has also reached Shimano - directly or otherwise) and it's taken them this long to issue some form of remedial action following years of "la la la fingers in ears not listinging all's fine don't know what you're talking about mate".
I don't think they've done themselves any favours re. the difference between advice in the US ("cease using") and everywhere else ("crack on, we'll take a look and if it doesn't appear shafted crack on; having signed away your rights should the unit fail in future").
Tbh as a generally paid-up Shimano fanboy I'm disappointed by this outcome / the way this has been handled and tbh expected far better of the company.
or 
winter?
