@annika I also think like @spiralganglion is saying, basically that the laws are mostly making a distinction between the following two things:
- having data technically available but refusing to share it with police (this can be considered illegal)
- having built a technical solution that works in such a way that no data is available, so there is nothing to share. Here the law would have to force rebuilding the solution to include a backdoor, more draconian and not (yet?) how most laws work.
