Please don't tar us all with the same brush. I have been invested with GW's mythos for more than half of my life, and still want to play a balanced wargame. The biggest issue is that GW see themselves as a miniatures company, while their customers see them as a wargaming company. The rules have equal importance as the models to most customers, while the rules are something to help sell models to GW. Until this disparity is fixed, you will always have people bitching about the rules and GW never taking active steps to balance their games as new issues arise, as most of those new issues are caused by new books, and power creep gets people buying the new models.
Unfortunately for GW, this is not the 80s or 90s anymore where the lack of a centralized way of publishing rules updates was unavailable. Their website is perfectly suited to store FAQs, amendments and balance fixes and the like. While the first is handled well (usually!), they do not seem interested in actively maintaining their game. Customer unhappy with their army do one of three things:
1) leave the hobby. That's fine, chances are your army was finished so you weren't contributing to GW's revenue stream anyway (i.e. buying more models).
2) keep playing anyway. Cool, you provide some flavour for people to fight against, help them with the hobby, etc. Win for GW.
3) buy a new army. Hurruh, you're now GW's favourite kind of customer!
I have been a gamer (as in electronic) for most of my life, and with the dawn of the Internet and especially multi-player games I expect companies to regularly balance/patch their games if issues arise. A lot of their current customers also come from the same generation, so GW's attitude towards the actual games can feel confusing, annoying and often insulting. Now I'm playing 40K properly again, I have come to accept that this is how GW works. Doesn't mean that I have to like it, or that I will be quite about it

Also, some food for thought: most of the issues with GW's games isn't down to the rulebook, but the codexes.
