I don’t think there is a contract here in most parts of the world. But maybe there’s an argument to be made for promissory estoppel e.g. by a company who moved from IE to Firefox based on these promises and spent $x moving to Firefox and now have to spend $x moving to something else in response to new information? In reality there’ll probably be nothing from this, though I’d love to see companies get punished for walking back statements like these.
