Do you work at Ubisoft or Black Hole? If not, then, IMHO, digging into someone else's dirty laundry is not the best idea. It would be good if at least half of what that Black Hole employee said in that remote message was true. It's not very fair to judge such things when we only know the position of one side.
The concept of "dirty laundry" still refers to personal life. In this case, I suffered from someone's unfair economic policy; I believe I have every moral right to express my dissatisfaction with everything that is happening, since I paid the price of a quality product for a semi-finished product.

That same message, of course, did not mention the mistakes that the Black Hole employees made. And we will probably never know if BH actually fulfilled all its obligations to Ubi on time. The game's release date, as I recall, was postponed at least twice. Therefore, as far as deadlines are concerned, I think it was more about extending them than shortening them.
