Smartphones and tablets are trying pretty hard not to be general-purpose computers. iOS devices don't run arbitrary user-specified code unless hacked, and many Android devices are designed not to let the user have real admin rights (i.e. root).
This seems to be getting worse, for example Google and its financial institution partners have decided that general-purpose computing and payments aren't safe together. Google Pay suddenly started refusing to do contactless payments on my rooted phone.
