But if you look at nonfree software developers, the ones who are very powerful, they can impose incompatibility and they are so powerful that the users cannot do anything. Microsoft is famous for this. They make an incompatible change in a protocol, and then the users are stuck with it. But it is not just Microsoft. Consider WAP, for instance. WAP contains modified versions of ordinary Internet protocols, modified to be incompatible, and the idea was they would make these telephones and they would say &ldquo;they can talk on the Internet&rdquo;, but since they did not use the ordinary Internet protocols, the incompatibility would be imposed on the user. That was their plan. It did not work, fortunately. But that is the danger you face when the users are not really in control: Somebody will try to impose incompatibility on the users.
