I think 'beyond repair' comes from the fact that there's not much "fixing" you can do. The margin for what can be fiddled is very small, as far as I have found when trying. You end up in "rewrite required" territory very quickly when you start trying to adjust things. "Fix" A, and B breaks. The solution Michael has of just making judgement calls is really the only way one can approach the product on its own.
Regarding fixes we might get from on high, given the volume of things stated as moving to the printers, and that this effort is on the same shoulders as the finalization of errata, my suspicion is that things which generate revenue will take priority over wrapping up the errata. Previous history also makes people rightly suspect.
Last thought from me is that it's also not really fair to SR to compare it to any other 'big name' (ie popular) product. The production processes and scale are very different, and this leaves the final product in a different league. I would agree the problems are at a higher rate and deeper nature than "standard" problem levels are, but I wouldn't call this product "standard" at this point. It is going to fail most any comparison test you put it to, really. The only fair comparison you can really make is to prior editions. Things like, "is it better now", "do you like X", "would you play it" are all valid. Comparing sales numbers, error rates, rules issues, fan reactions, community engagement from management, responsiveness of customer service, marketing strategy...this just isn't that shop, and it won't be for the foreseeable future. SR6 and CGL are going to lose those comparisons almost every time. Don't waste your time.
It's disappointing to me too, but I can't change that. "Management" has stated they don't want to act on the negative feedback since it 'doesn't represent the player base', apparently. Folks who want changes will just have to wait and see if anything trickles into the supplements that addresses any of the issues. My guess is you'll see it there before any errata addresses it. I will happily eat those words if I am proven wrong.
