For example, maybe they weren't being sleazy and they thought this was a clever play off Tesla. It isn't clever. It is unprofessional. It also shows a lack of clear vision in that they are fundamentally defining a company based off being an alternative to competitor. This shows a lack of leadership.
Or maybe they are even stupider than we gave them credit for. They saw the company was named Tesla and assumed Nikola Tesla had a direct hand in designing electric cars and were too lazy to look up the rather tangential connection between the man and the company. This shows a lack of knowledge or desire for knowledge.
I couldn't think of any positive reason for the name.
