Having direct business to consumer relations with the people of a country is doing business in that country, even if the multinational corporation claims otherwise
i have not checked every service affected in Nepal, but i would assume most of them require a user account, which includes agreeing to a contract that establishes a b2c relation. Such a relationship does not necessarily require payment, and is not at all comparable to calling someone.
That's like arguing a Seattle coffee roaster is doing business in Nepal because someone in Nepal called them on the phone.
