The operative word being "truthfully".
I have yet to see any evidence of lying. Accusing PE and EM of lying about funding and/or possible production dates really does not mean much without evidence.
We all know circumstances change and funding which was thought to be committed may not be there forever so there are plenty of perfectly valid reasons why these statements would need to change over time. Much of this information is also highly confidential and not able to be discussed publicly. Along with that publicly shaming your investors, even if no name is used, is also not exactly a smart move for a company seeking new investors. Investors are the life blood of a start-up so it is in EM's best interest to fully honor their commitments to their investors and to keep negative comments about investors private even if an investor may have really screwed them over.
As for the production timeline, everything I know says this vehicle could actually still be built this year if development money begins showing up in the next couple of weeks and the production funding begins showing up in the next couple of months. While I doubt EM will push this hard, as they have now bought more time with the plant extension and don't necessarily have to rush, as long as they have running engines about four months from now they can still have six months of testing under their belt before entering production in the 4th quarter and during this same six month testing time period they can likely get the plant online and be ready for production as Comau has already mapped out what needs to be done.
