It is confusing. If you have two apps on your phone that do the same thing, how is the new user supposed to know what to do? I’m thinking of Samsung and how they insist on shipping their own branded stuff that, for the most part, brings nothing new to the table.
If RCS is such an awesome standard, why not mandate it for all EU phones? Apple already supports the current standard, which is SMS. The idea that they have to open up their proprietary software seems silly to me.
