I don't know, to me the statement begs the question "So why wasn't it a great fit?". People are going to speculate regardless of an announcement from you, if it were me I would prefer to just keep my head low and let those who really care to know/I care to tell ask me (or Tesla) personally without a bunch of unneeded commentators jumping in and potentially putting negative connotations in my mouth.

But I hadn't seen that Telsa released a similar statement, and that changes the context quite a bit to match what you describe.
