Well, I do not propose to get involved with rants, so how about a more measured approach?
Let's start with the Seafire. It takes off perfectly well from a carrier both via autopilot and manual. In this case I actually used one of the worst carriers to launch from - HMS Furious - simply because I already had that CV in a test mission. It has no catapults, and a weird multi-level flight deck, yet AP and manual takeoff were fine. So the Seafire works - the problem, as I suspected, lies somewhere else.
By no tailwheel lock, do you mean that aircraft that once had a working lock no longer do so? If so, please be specific so that I can test them. If not, with somewhere around 1,000 aircraft (I think) in BAT, there are certainly quite a few with no tailwheel lock modelled. Same with opening canopies and instruments. It is what it is - some aircraft are not always finished to absolute completion, but are released in 'good enough' condition to fly in the sim. That seems fair enough to me - what do you think? Also, would you consider no tailwheel lock and a non-opening canopy to be an absolute deal breaker? Personally, I would rather have the aircraft in the sim than not. After all, with such a vast choice you can always opt not to fly an aircraft you don't like - there are plenty more to choose from.
Finally, many of the added aircraft have errors corrected and improvements made over time, sometimes by the original author, sometimes by others. Take a look at the recent work on seaplane cockpits by Asura, to take one example. This is an ongoing, dynamic project, with gradual improvements over time, undertaken by amateurs at no charge - it is never going to be a finished article 'out of the box'.
Yours,
