Thanks for doing this, but there are a few problems.
(1) we should assign the copyright to the author of the file, not Music Blocks/Sugar Labs
(2) in many cases, you removed important context from the files (all of the files in API, for example
(3) there are many useful but unrelated changes that should be in a separate PR
(4) upstream config files that we are using don't need to be modified

Thank you for the feedback! I’ll work on fixing these points, but I have a few questions to clarify things further:

1. Are you the author of most of the files in the project? If so, I can assign the copyright to you in the license headers.
2. Regarding the unrelated changes, if you’re referring to the changes in the _() method, there’s already an open PR Refactor _() function to improve translation handling and case preservation #4476 for that. Could you please check it and let me know if there are any additional modifications you’d like?

Thanks for your guidance!

Let's focus for the moment on just the files in the test directories.
You can see whom is the original author by looking at the git commit logs.

Done #4482.

Whats is the next step ?

[walterbender]

Let's revisit these changes in light of the updates to the test files.

Seems that the license text in js/SaveInterface.js, js/blocks/*js and js/js-export/API need updating. But be sure to keep the original author info. And please preserve the comments in the API headers that are unrelated to the license. Prob. a new PR makes sense.
