they'd still get mad at Philips when a third-party bulb breaks I don't disagree with you -- a subset of customers are going to be angry regardless of warnings, they only go so far. But the issue at hand is how best to deal with the problem they have publicly stated was the reason for this decision: Some subset of third-party bulbs do not work ideally in their ecosystem. Option #1 was to warn customers of this problem and let them decide. There are several other options that were available to them. The farthest down that list, and worst option they had was to disable the bulbs. I would expect that last option to be used only for bulbs that caused fires or other safety issues. That wasn't the case (or I would have expected them to have stated that directly since it would have been something a lot of people would have understood). I don't think Philips realized how major of a feature this is, particularly to early adopters.
