The article is short on details. Schrems alleges that Facebook somehow picked up his sexual orientation from a panel meeting, and then advertised to him based on that? Is it not more likely that the group of people/profiles and activities he participated on Facebook are what "outed" him instead? I had hoped for more details about how Schrems and/or a court were able to prove Facebook took his off-site meeting into account and based ads on that alone.
