But, for that example, it depends. So if Shopify adds Hibiki to their site, and then writes a custom module that integrates Hibiki into their API. And then they add a new tab to their webpage builder that says "write your form in Hibiki HTML", then no, that would not be okay.
If they just have a generic form that accepts HTML, and makes no mention of Hibiki , and you manually add your HTML which happens to include the Hibiki script and runs Hibiki code, then there is no issue.
I'm curious--why all the weird license stuff? I mean, I understand what it allows and doesn't allow, but why did you decide to do it that way? I don't honestly know if a non-open-source framework has a legitimate chance of success in 2022 with so many strong open source competitors. From the response here on HN I think you can see that this is a pretty major issue.
