First of all, Marriott hasn't officially pulled all newspapers out of all hotels, it's just stopped having the requirement to have them, and thus left it up to each hotel.

Second, I don't think airline lounges and hotels are comparable on this. Newspapers in airline lounges are often taken onto the plane, and read during take-off/climbing, when onboard WiFi is not available and thus there's no other way to read a newspaper other than a physical copy (unless you managed to get the whole newspaper downloaded onto your laptop or mobile device beforehand, not just one or two articles, but AFAIK that's not possible with most online). But hotels don't have the same issue that people can't access WiFi.
