Whether or not they lied is in the end an implementation detail - a skilled amoral persuader doesn't need to lie to mislead. The toolbox for that includes being biased in what facts you mention, making "mistakes," and using your own words to connect the wrong dots (basically every way to introduce an error can be abused). Tesla claims that the reporters are focusing on a healthcare provider that they cut ties with while ignoring what they are actually doing at present - which is one example of what you could do to make your readers believe wrong things without lying.
