terms of service, there is a grace period before all oculus accounts will have to submit to the big brother via terms of service agreement or have to get a new headset to replace their expensive paperweight, i think there is still 2ish years left to swap headset before zuckerberg makes it mandatory for all oculus accounts to link to facebook
right now it is highly illegal for them to spy on euros with their TOS bullshit so not sure about future of oculus in EU, then again when did yanks ever respect laws of other countries so who knows maybe they'll find some loophole with their legions of lawyers that allows them to push it to EU market with their privacy violations intact 
TLDR; law of the land in most of EU
