That's a very interesting situation for two reasons:

1. Arguably your matchmaking data is someone else's as well. Meaning, they'd be potentially exposing other people's data to you.

2. Arguably you don't own the matchmaking data. You only own the initial request for matchmaking. The end result is actually a product of their proprietary algorithm. You didn't generate it.

Perhaps it might be a good idea getting in to touch with a privacy campaigner, or if the European equivalent of ACLU exists, and have them test this in court because it affects two different and important aspects.
