Eddie Jordan won't back down from telling it as he sees it despite Mercedes boss Toto Wolff accusing him of spreading fake news.
In Baku, Wolff lashed out at the former F1 team owner turned television pundit for continually claiming Mercedes will quit the sport after 2018.
"I told him that this is very serious for me," Wolff said.
"He should stop reporting these rumours -- this fake news."
But Jordan is hitting back, denying first of all that he actually said Mercedes would quit Formula 1 on a specific date.
"I just said they are in F1 for marketing and technical reasons, not for charity, and they will go when it suits them," he is quoted by Speed Week.
"I just said the contracts with Petronas and UBS end in 2018. I can understand that Toto is angry about it, but that's not my problem, that's life," Jordan insisted.
"If I say such a thing, I say it with conviction.
A Mercedes spokesman said Jordan was wrong however, insisting that the manufacturers' contracts with UBS and Petronas expire after 2018.
"He talked about the 1500 employees, but I'm talking about thousands of shareholders, and a decision that the executive board will make.
"If they find that the investments are no longer justified, they will be gone."
Jordan therefore insists that, despite Wolff's anger, he will not be silenced.
"My job is to tell people what I know. And that is exactly what I will continue to do.
"I have no problem with anyone," Jordan added.
"I can go to any motor home, and if someone thinks I should not, they should tell me directly."
