It did NOT say the virus was definitely released from a lab. It did NOT present any evidence it was. All the article said was that given the author's experience with labs like this, she thinks the chances the virus escaped are not as remote as the scientists investigating it claim it is. That's all! Your theory might be correct, but as of now, you have no reason to think you've been vindicated.
EDIT: author is a woman, so fixed pronoun.
