Commercial Use License - how is it?

Question

Copyright

I want to try Caddy Server. Which seems to be open source, but the authors ask for a paid license for Commercial Use - https://caddyserver.com/products/licenses

If your company uses official Caddy binaries internally, in production, or distributes Caddy, a commercial license is required. This includes companies that use Caddy for Research. The personal license is appropriate for academic research, personal projects, websites that aren't for profit , and development at home.

And then I thought. Well, ok, if it is used at the enterprise - there are no questions at all, everything is according to the letter of the law.
1. And if a private person, then where is the border of websites that aren't for profit ? How is it proven? Yes, let's say even if I have an online store, but at one loss, i.e. without profit, then what, haha? After all, you can draw any accounting department with a profit.
2. Assuming you can score. What ways does the author of this software have to "shit"? There it seems like the binaries are downloaded. Can he put some kind of DRM in there? What can you really be afraid of (harm, hacking, failure, etc.) in the case of Caddy? Let's say that I don't give a damn about threats in court - there's nothing to take from me.

Answer 1

commercial use - use that involves making a profit. there is a profit or not - it does not matter.
none of the sane will deal with hacking and harm. can:
- score
- sue
- blacklist the domain
- refuse support
- limit functionality
- etc
