Elon Musk didn't even directly advertise Dogecoin. He just mentioned the name of this coin, wrote that it would skyrocket in price, really stated that Tesla would accept this coin. It is impossible to tell the Mask something here. Everyone can express their personal opinion about any events or things. So what Elon Musk did in relation to the Dogecoin coin is his right. Not everyone can agree with Musk's statements and actions. But this is also their right. Therefore, I am sure that the claim will be rejected.
