I like your willingness to make the efforts but I honestly believe his responses denote an air of aloof superiority and an unwillingness to admit error. Such reporting is irresponsible and only serves to alienate him from any reputable colleagues and/or associates.
I do not think that Workhorse would give any credibility to this person's reporting by answering or acknowledging it in any way. The company states their activities plainly and honestly. They have released vast amounts of information into the public domain for years and would most likely see no need to repeat it or defend itself against such inaccurate statements. Besides, they're a little busy right now. 🙂
Just my opinion.
