So basically drone.io is saying that discourse is not RGPD compliant and reddit is better equipped to deal with RGPD requests so he's moving his community discussion from a self hosted discourse to reddit.

Looks like a knee jerk reaction and missing the point that you can evade RGPD by outsourcing to a third party, one can still send RGPD requests to drone.io and owner is still responsible for answering those but now has to deal with getting the relevant data from reddit.
