tl;dr:
- The primary reason for their arrest wasn't the Linux/encryption tools.
- They were under investigation / suspicion after volunteering for a Kurdish militant group.
Secondarily to the above, the prosecution used their encryption/etc, (in a case of bad logic) as further post-hoc evidence or cause for suspicion.
In my opinion, omitting the primary causes here is intentionally muddying the issue, and making it sound like encryption itself was the cause.
*Caveats:*
- Yes, the prosecution clearly don't understand the technology, and obviously don't care to know.
- Yes, they are implying that use of encryption itself is due to "needing to hide something".
- Yes, they're implicating innocent (AKA "normal") use of encryption as something bad, and that's a problem.
