It hasn't met the milestones laid out at the start at any stage, it still hasn't flown in any form, the performance therefore is completely unproven and the costs are rising.
By any metric, Hill has not achieved what he promised to do.
He MIGHT get an aircraft airborne in the next year, it MIGHT achieve certification, it MIGHT have the claimed performance and it MIGHT be produced 500 per year - but so far just some glossy videos and lots of spare parts.
If you look back accurately you will see that most of the 'negative nancies' would like Hill to succeed but rail against constant overpromising and under-delivering
