"Nevermind, I'll enjoy listening to their 'Near Miss' and 'how I heroically avoided disaster' stories at the airfields I visit or reading their obituaries in the press."
Cynical - probably, helpful - doubtful, funny - best not to joke.
I think you have totally misunderstood the posts.
Everyone, including Mono, accepts that in some circumstances the use of the radio and transponder may help avoid a collision in open FIR. However when you have been flying a bit you realise that the contribution these tools make is minimal.
As I hope I pointed out there are many other ways that can be employed that are more likely to reduce the chances of a collision. I am sure Mono is very adept at these techniques and is probably a far safer pilot than those who turn on the transponder and make various utterances on the radio thinking this is all they need do for collision panacea - and there is a lot of those!
Some wish to preserve their right to operate non radio, non transponder equipped aircraft. Unfortunately that right is unlikely to last much longer, but as is so often the case these rights may well be lost on grounds of misconceived improvements in safety.
If all aircraft were equipped with mode S and cheap mode S reliant avoidance kit was available (and it certainly could be) then this technology would come into its own when the whole fleet was so equipped. That may well be a good idea at a realistic cost. Until then you will get no real traffic avoidance service in open FIR - just try flying in France and you will be lucky to get a FIS most of the time.
Until then take on board some of the comments on this thread and by all means switch on your transponder and use the radio (I personally do so every time, and my transponder is mode S) but please don’t assume that will help at all in avoiding a collision. Follow some or all of the other techniques for reducing the chances of a collision and Mono and I and quite a few other posters on this thread will feel a lot safer. Respect the right of some to fly non radio non transponder because the law permits it.
