If you have not encountered any issues with laser ranger resetting to 0.1/0.2 you have not played much Black Shark the last year or so. This is a game breaking bug in multiplayer, I don't fly SP, so I can't say if this bug exist in SP.
And yes, it's fair to say the Ka-50 have been abandoned. Look at the patch notes 12 months back, and then compare with the bugs that are introduced, and left to rot patch after patch.
If ED don't feel the need to update and patch the Ka-50, release the source code to a 3rd party dev so they can continue to work on the shark. Win-win.
