No it isn't. You just add the license to the project and files and then upload it to anywhere on the internet. This takes like three commands total. Any professional dev that's not a webdev should be able to do this in less that an hour for everything.

For the extension, the repository has no previous commit history suggesting that they did not use version control or they are too stupid to clean up their mistakes so they nuked the old repo.
