Samsung's continued knee-jerk reaction to anything that Apple does never ceases to amuse.
Thanks. In which case I think saying Mapzen is "backed by" Samsung is a bit of a weird way to put it. Mapzen is a division of Samsung, they're in that Venn diagram. I don't think it makes much sense to say that you back something that you own.
That is because they plan to rebrand the company as Sam-zen-g at some point!
