Yes, the argument is wrong. Freedom 0 allows User A to run their own instance of the F-Droid server as they wish. It does not allow User A to compel User B to run User B's instance of the F-Droid server the way User A would like it to be run. If the argument were true, any user would be able to control another user's instance of a free software network application, which would be a serious violation of property rights. If User C's instance of the F-Droid server hosts a repository with Gab in it, and User D connects that repository to their F-Droid client, the client would be able to download and install Gab. This shows Freedom 0 in action.
