I too am experiencing the problem with Github. As more sites implement CSP this problem will grow. I noticed that the 1Password plug-in works fine. I guess, if CSP is the Web Clipper's problem, 1Password doesn't reach out the Internet. Is it possible to have a version of the Evernote browser plug-in that doesn't violate the CSP? Maybe it can communicate with the desktop application or degrade gracefully so some of the functions work. It's more important to get the idea, the clip, into Evernote than it is to get the related notes and such.
