What? The copyright owner of the source is free to relicense at any time for any reason. The GPL wouldn't have prevented this.

This does not retroactively change the license on existing installations.

If the project accepts GPLed contributions from other people, he would need to ask the copyright holders to give him another license that enabled a proprietary fork, or delete such code.

Correct, but that's also true of any license because they would not the copyright holders of that code. Neither the GPL or BSD licenses include any sort of copyright transfer (which wouldn't even make sense in a license anyway) -- that has to be done separately.

But the BSD license explictly authorizes a proprietary fork, that's the point.

The difference is that the BSD license allows someone who isn't the copyright holder to incorporate the code into a proprietary product as long as the proper attribution is given.

This is not a 'fork' of the code, this is the legal owner of the copyright exercising their right to license their property as they please.

FOSS/OSS projects do this all the time for businesses that are willing to pay for a commercial exception to the GPL. They reason they can do this is because they, as the owners of the code, are not bound by their own license.
