The company has a right to terminate provision of the given service at any time for any reason. This is very surprising given the fact that most people have entrusted the company to handle their communication for the long-term and that their Yahoo! accounts have been used as points of correspondence in the future. This therefore makes it very uncertain what would happen if Yahoo! were to discontinue their services. Yahoo! can therefore pass for an unreliable entity given this clause that undermines the user's chance to sustain their use as they please.
