Based on the 2019 court transcript linked in the post, the reason for keeping him in jail during the pretrial are a lot more reasonable than how this is framed in his wife's post.

The FBI said he downloaded a client, here Spice, which can be used to access a VM and visited the tor project website to look into how he could download a Tor client. That happened in the 24h which followed him agreeing to electronic monitoring and voluntarily installing a spyware. They argue that he has the knowledge and mean to circumvent the monitoring he agreed to and his pattern of actions indicate he is likely to do so if left free. A huge part of the argument lies on him having agreed to voluntarily participate in his own monitoring. The CFAA charge seems to be sealed but I'm far from convinced it's a minor work related issue.

If you read the website, they keep firing their attorneys and pretending they are colluding with the government to keep him in jail. Parts of the description are frankly bizarre. It seems they are actually suffering for paranoia.

I would read the post with a huge grain of salt.
