This is exactly the kind of entitlement the OP mentions. Also, how would you know your product you wanted to release was going to displace everyone in the market? Does this apply only to large companies or is it small shops as well? What if they lose interest or what if they lost users when they add this magically and universally loved paid solution? There is no such ethical responsibility and they shouldn't be because it is ridiculous. Google shutting down Reader might make them tools, but the precedence you're trying to establish with ideology like this is far worse than that.
