Those two are not the same, see https://www.gnu.org/philosophy/selling.html

You can also try to charge $10000 for a gold plated CD copy of the Linux kernel without having committed a line yourself.

You can charge for the source code too, just not separately.

But you can definitely have an opensource project that is not available free of charge from any official source. Your clients can redistribute for free or not, but you are not required to just let the whole world have your code directly from you.

Of course you can sell copies. My point is exactly this part of the article you've linked:

"With free software, users don't have to pay the distribution fee in order to use the software. They can copy the program from a friend who has a copy, or with the help of a friend who has network access".
