Re: @AC - I understand where the dev is coming from but ....
And that is my entire point. BSD is relatively tolerant of relicensing which is how BSD code can end up in GPL projects in the first instance. The reverse is not permitted by the GPL. Once the code is within the GPL any changes made to it can't be back-ported to the BSD project because the GPL expressly prohibits that kind of relicensing. Hence GPL projects are free to leech from the wider open source community but don't give back.
In the context of the current article it also means that projects can't be relicensed. If circumstances change making the project unsustainable it dies as a result. Sure, someone else can pick up the code under either licence but someone has to do it: if it was a given there would be no market for a commercial offering.
