in a post about [checks notes] FOSS software development, puts things in a certain light.
FWIW I'm privacy-conscious myself. If the author had just made a general effort to point out the privacy implications of using Discord, that would be one thing. Instead he made a contrived effort to connect it to FOSS development - arguably one of the least-private activities one might be doing online - and then went on to call Discord altogether "unacceptable", instead of just saying "don't assume that what you say on Discord is private".
If you're referring to what I think you are, then no, his "crime" was publishing a product that was not allowed to be exported to the public (effectively exporting it). You're statement is equivalent to serving poisoned food and saying you were prosecuted for the crime of owning a restaurant.
No matter if you agree with the export ban or not, it was a law and Zimmerman broke it. That's what he was prosecuted for.
* - except for things like Signal, Tor..., which are illegal some places, but they probably wouldn't even consider Discord in the first place
Creating (or in this case distributing) anything that's against the law could get you in trouble with the law -- kind of how it works.
