There are ways we work today that would have given a last-century HR manager a nervous twitch. There's employee collaboration, file-sharing, and general chit-chat, over less-than secure cloud services. There's employee adoption of new third-party services such as Expensify and Yammer that, once they've Trojan Horsed their way into a company's workflow, are impossible to extract. There's BYOD.
If you think this is a problem, I'm part of the problem.
In addition to, well, all of the above, I've repeatedly booked lodgings on Airbnb for business travel. Beyond basic math and logic, I didn't really think about it: It was less costly than a nice--or even medium-nice--hotel, more central, and more comfortable for me as a working traveler (free WiFi; ample coffee). It just made sense. I've hailed for short work travel non-cab car services--Uber, Lyft, and the like--when it was logical to do so. My editors do the same. (Based on the responses we got to a Facebook post inquiring, many of you do the same as well.)
