@scottalanmiller I am just concerned about its 'virality' clause. That if for some reason my program is considered to be distributed, I would have to open source the entirety of it.

1. I have read that if the server sends javascript to the user's browser, that is considered 'distribution' under GPL. Is that true?

2. Would the manifests and service workers of progressive web apps be considered distribution? Since they store a little bit of cached data on the user device itself?
