That's a very curious article. I read a lot about how Russia was involved, this one cleared many things up. And besides, did you translate the part in the end, where it says that venezuelan government didn't even pay them?
I read the article and I checked all of the articles of "awritwewithfreedom" and I found that almost all are biased attacks, without factual references, on Venezuela, included the article about Petro. So, why should we believe anything this article says?
And, I add, I'm convinced the Venezuelan government hasn't been handling this matter correctly, offering sufficient and timely information.
