I think the typos were intentional, just like with Trump’s tweets. They know how petulant the main stream media is and by putting blatant typos out there they know the media will inevitably draw attention to the tweets or documents so more eyeballs will be on them.
I think this is the answer. I have also read that the documents sent to the court did not contain those errors. Brilliant, if true.
“I think the typos were intentional...”
I agree it is possible. Criticizing the spelling errors makes people read it before being told what it says and, more importantly, I think, gets the bad guys to do most of the advertising.
