Re: EOS 5D Mark III & Third Party Batteries
I bet if a few hundred recent DSLR purchasers updated their firmware, then sent the cameras back to Amazon, saying that the firmware update caused their camera to stop recognizing batteries, Canon would change their tune pretty quickly. And by "quickly", I mean that with a few hundred returns, Amazon would automatically yank the affected products off the market pending an investigation, which would make it the single most expensive mistake any Canon exec ever made....

Nobody in his right mind should expect Canon to care about their competitors and they have absolutely no obligations to them. Although, one could argue that a working ecosystem of third party accessories is one of the key advantages of established camera brands ...
IMO, it's a mistake to call battery and lens manufacturers "competitors". Canon isn't a battery manufacturer. It's a camera manufacturer. They build minor accessories, such as batteries, for one reason and one reason only: because the batteries must exist for the cameras to be usable. Accessory makers expand their ecosystem and make their actual core products more desirable. Anything that Canon does to harm those accessory makers harms Canon doubly.
The situation with Canon and lens/battery/flash manufacturers is a bit like Apple with third-party software makers. Microsoft Office '08 and Photoshop CS3 still work in the very latest version of OS X even though they are both over half a decade old. And there are plenty of Windows users out there who still run random apps from even farther back. The reason those old apps still work is that companies like Apple and Microsoft go out of their way to minimize breakage of third-party software.
IMO, Canon has a similar responsibility to minimize breaking of third-party accessories unless it is truly unavoidable. Anything less is unconscionably abusive.

But this protocol change, as documented in the dslr-forum.de thread, did not hurt Sigma as much as it hurt Canon's existing customer base.
Indeed, that's almost invariably the case. Unless Canon managed to find some way to break compatibility repeatedly and often, it isn't likely to appreciably hurt Sigma's sales. If anything, it helps Sigma by breaking compatibility for their older products, thus forcing users to buy new lenses (most of which probably won't be Canon's, because if cost were no object, they would have bought Canon lenses to begin with). Worse, it hurts Canon's lens sales by forcing users to replace their existing low-end lenses for no reason instead of spending that money towards more expensive lenses that might actually be exclusive to Canon.
Now obviously the same logic doesn't really apply to batteries, but I dare say that given how hard it is to actually obtain genuine Canon batteries, this won't significantly increase Canon's battery sales. Either way, IMO, the battery situation is just a symptom of a much larger problem with the way Canon's upper management sees its customers. These sorts of vendor lock-in games tend to be a quick path to bankruptcy for most companies that are foolish enough to play them, and Canon would be wise to correct this craniorectal inversion sooner, rather than later, before the bad taste it leaves in their customers' mouths causes many to reconsider their relationship with Canon's products.
