You’re not reading it correctly and you’ve been answered already. ??
The GPL is all about software rights and distribution. It does not say anything at all about where the code is downloaded from. It does not care at all.
Asking about paid, where it’s coming from is like asking if the GPL talks about rain on Mars (it doesn’t). Your questions are these.
Does the GPL license also allow free updates and downloads directly or a file?
I’m going to ask if I’m allowed to use updates and downloads under the GPL license even though the updates are coming down from a server whose owners don’t want to give updates to anyone who doesn’t pay them.
The main question is do you have a link to it that says the obvious answer to that.
It is unlike anyone who has paid a fee, and it then transfers to someone else.
The answer is the same: the GPL says you cannot restrict distribution of the code. You cannot prevent users from using that code, from distributing that code, from changing that code, from distributing the changed code.
GPL code can’t have those restriction. Asking these questions about where the code is downloaded from, who’s server, who paid or transfer or fees is not about the GPL.
The GPL is about those questions as much as it is about rain on Mars. Nothing in the GPL is about that.
