The key is that, while there is suspicion (the people arrested have a far left ideology, have been to Syria to fight against the Islamic state, own weapons and encrypt all of their communications), there is no crime nor proof of an intent to commit a crime.
These people have been sent to prison because they are suspicious, not because of an action they have done (something made possible as a special case of an older antiterrorism law). And, amongst other things, using Signal and Linux with the encryption-on settings are explicitly listed as some of the things making them suspicious in the eyes of the law.

That is a slippery slope.
