I only use Linux and indeed, drivers work OOtB and don't require you to sign any privacy policy. Although you don't have the fancy GUI that they have on Windows.
The Huion GT works OOtB with the Wacom drivers. For the 1060+, I tried all the out-of-tree drivers without any luck, but that was about 3 years ago.
Also, being fully open source I don't think the Linux Wacom drivers do any of the shady stuff the Windows ones apparently do.
