They have for a long time, but it's only an issue if you share a file publicly. If you just keep files private on your Drive, or share them with specific other accounts but not to anyone with the link, there's no copyright scanning.

While if you're just backing up your CD's and DVD's for personal private use, everything works fine, zero problems.
