Widevine DRM demands your “video player” to download a very specific module signed to your platform. In the case of Windows, it will be the file widevinecdm.dll and for unix like libwidevinecdm.so that the host will save in a proper place and register it (load the decoding capabilities). If you use Netflix, your “player” does that, many apps in most machines are doing it right now in the entire Europe… one example of a package being downloaded after the player sending the proper request from a AMD 64 extended x86 CPU from a Linux host using the Widevine engine 4.10.2557.0, is https://dl.google.com/widevine-cdm/4.10.2557.0-linux-x64.zip
If Europe is going to get in trouble with it, the video streaming market in Europe will be in trouble.
That said, not sure if some Xojo user plays protected video content, probably 99% not, and hardly someone will be affected, but disabling it is simple as including an optional argument to the compiler call.
