We do understand and share FS9 users' feelings, but we announced the Block F (757 2.0) to be the last FS9 release years ago. So there was no tricks or surprises. Our clear message was(is): Keep current - switch to FSX!
We even released version 2.1 extra.

Unfortunately we cannot afford working for two quite different platforms anymore.
So development for FS9 is over (long time ago), all FS9 titles are at bargain sale for 9.99 as is.
There is no way back, we have to move forward.
