First of all, I see this as more of a moan than something being saved from otherwise being sent to scrap.
Secondly, if you want to moan, why not direct your dissatisfaction at the DfT who are refusing to allow the 150s to be leased to another operator. It’s little secret that the DfT wants the Mk3 based stock gone, the 769s (unluckily for Northern) only curry favour due to their (just about) Bi-Modal capacity. Whether or not they work is a different matter which, from the Northern 769s thread, we know they don’t particularly well.
Anyway, congratulations to Porterbrook and the Watercress Railway for being the first to take on one of the Sprinter’s. And no, the two 153s on the GCR don’t fully count as they are owned primarily for commercial purposes.
