I don't think that the outcome of this fight will have any impact on those airlines whose conditions are already appalling when compared to BA, or other flag carriers. In my airline, we wonder in envy at those T&Cs and associated perks, and there is no way my airline could or would ever match them, no matter what the outcome is. I suspect some people take the envy to an unhealthy extreme.
Certainly, if it is your desire to work for BA in the future, then you should care. If that isn't your bag, then I don't think it does matter. But perhaps I am missing something? Why this juncture, why not in the past with BA Connect, or GSS, or even GO - what's so different about this? The 100+ seat argument is lost on me, but I'm not very bright.
