I was always convinced that Skype was bought by microsoft so CIA/US intelligence agencies to have listening capabilities.
The first thing Microsoft did after the Skype purchase was making it easier to tap into the calls by removing p2p calling and routing calls using centralized servers.
The catch is, views like those must be kept to a fairly modest level by the people who hold them. Discussing them with ideologically aligned colleagues may be fine, but for example, when someone makes statements or asks questions with such pro-privacy framing on stage directly to security leadership at internal company conferences, that is a quick way to a severance package not only for the person on stage, but also for dozens of folks in the audience who clapped a little too enthusiastically at the onstage remarks.
