The people distributing can claim a fee for the sourcecode, but it's
limited to "cost of physically performing source distribution".

He can do so with or without to charge a fee for the re-distribution (e.g. from his website). I think the GPL allows explicitly to charge for the redistribution. So, he would not violate the GPL if he would do so. Is this a correct interpretation of the GPL?

Not true. You can make money programming free software (my bank account
will confirm this) you just have to change the way you charge. With
proprietary software you charge per use, with free software you charge
per improvement. I prefer the latter.

The copyright holder can choose any license he/she/it wants for its
software. Just because they publish under the GPL there's no reason not
to publish the same software under another license if you're the
exclusive copyright holder.
