I think bad support for the Galaxy S will, in the long run, decrease sales of future devices from Samsung. If customers are interested in long supported devices, then the companies who provide them will come out on top. And if customers don't care about updates, then they won't buy a new device just because it has a newer version. There are already some device vendors who provide good support: Google and Apple. Others, like Sony and Asus, seem to be willing to improve their reputation. Samsung itself has already improved a lot since 2010. It's disappointing that the Galaxy S is abandoned now, but it already got a great deal more support than Samsung's 2009 lineup. Also, don't forget that Motorola is going to be part of Google soon. For obvious reasons, future devices from Motorola will run AOSP-Android and get Android updates for as long as possible. tl;dr if customers want long term software support for their devices, someone will give it to them. No matter what software platform the software is based on.
