"Digital rights management" (DRM) status for Tor Browser for each OS

I'm not talking about if DRM has been disabled by default but if it is completely removed.

• macOS: ?
• GNU/Linux: ?
• Orbot: ?

Please provide at least one reference (https://trac.torproject.org/projects/tor/ or release notes) for each answered OS.
