The slot discussion thing was definitely not nonsense. You should read the CAA reports when the OL was revoked. They fought damn hard to keep those slots and have them transferred to the new airline. They weren't successful. But let us not pretend they didn't want them - for what exact reason we will never know now.
I wish the new Flybe well. They're legally entitled to start and fight for their place in the market and the other airlines will have to adjust to compete. I'm just incredibly sceptical as to how successful it will be. People are allowed to speculate on a forum about that and I wouldn't say it's necessarily 'negative nonsense' anymore than I would want to describe posts on the other foot as 'happy clapping.'
