That article seems to just assume that Moderna are acting in bad faith there, without a lot of evidence. Certainly if they wanted to be obstructive they still could be, but the article-writer doesn't prove it either way.

I'd be interested to know if that's been tested. For example, have any other companies or countries proposed making the Moderna vaccine at all? And what happened? Co-operation? Grudging support? Full-on obstruction?
