Police conducted search in the Nginx office due to a copyright claim

I think you will run into conflict of interest issues with having your employer pay you to use your product. It might fly at some places, but I would be hesitant of running afoul of all manner of issues if there could be a perception that you are leveraging your employment position to profit your own company. Especially if your employer accepts money from the government.

I agree with the first two though. I personally am leery of suggesting the use of my own products and services to a current employer, and would only do it if it's very clear that there's both not other great options and that there's not a conflict of interest (decision maker is in another department for instance) and recognize that I may need to quit my job to avoid the perception of a conflict of interest or legal issues with government grants or other awards that may prohibit employees from also being vendors.

It's definitely riskier than just not using your personal projects at work unless your employer is actively pursuing using it fully independently (ex: your project is the only good solution to a problem and it's unreasonable for your employer to be the only people who can't use it). But even then, I'm largely unable to do work that only I can possibly do (i.e. I worked on two projects as an independent contractor for my current employer before they were my part-time employer) for people in another department despite being part time simply because it's too much of a mess to get it approved. I could probably get it done, but it's a huge hassle and not worth it for $1.

But your current employer might also take major issue with you having a side business selling to their competitors stuff that they want to use, regardless of the technical legality... at the least you might get fired even if you've done nothing legally wrong it might be against their employment guidelines to do this if you're a full time employee. I specifically chose to be part time because I still do contract work on the side (and make more money doing that than I do at the part time job, but I really enjoy my part time job so I don't mind).

If they own copyright.... Which isn't crazy...

Then the licenseing Igor put on it is null and void I assume, so everyone's instance would become illegal upon that court decision?

Especially for the Front Side Bus crowd

Not trolling... if they outlaw encryption, as most governments want to do, it will require creative org structures.

This is a new level of copyright trolling.
