If you say “we don’t want eu clients” and actively try to keep them away, to me it makes sense not to be liable anymore.
I feel like it’s like, let’s say this scenario. I’m pretty sure in Germany it’s illegal to host content promoting nazisim. Let’s say a hacker posts against all measures taken by the company content that is against the law. Should the german website be held accountable for content they unwilling hosted for a time? Shouldn’t the fact this was done against the wishes of the platform matter?
I might be wrong technically with the german example but the point still stands. I don’t think a platform should be liable if it’s in breach of a law against it’s wishes, if it has reasonable prevention and mitigation measures in place.
