Probably because Nintendo realized that the idea to make people use their console more regularly by means of non-gaming apps eventually turns the console into a non-gaming machine, because it's hardly used for games anymore.
But that would mean Nintendo said no to those apps to the Switch, which would be weird, since that could bring bad press to the console ("Nintendo forbids companies from bringing services to the console" kind of bad press). Why would Nintendo say no to other companies developing sevices like those? Seems like nothing that Nintendo should bother about.
You know it deserves the GOTY.
