Jack Dorsey, co-founder of Twitter (now X) and Square (now Block), sparked a weekend’s worth of debate around intellectual property, patents, and copyright, with a characteristically terse post declaring, “delete all IP law.”
X’s current owner Elon Musk quickly replied, “I agree.”
That’s what would happen if copyright doesn’t exist. If a company releases something, it’s immediately public domain, because no law protects it.
The GPL is very much not the public domain.
The GPL is basically trying to make a world without copyright. The GPL basically only has teeth in a world where copyright exists. If copyright didn’t exist then everything would be in the public domain and the GPL would be toothless, but that’s fine because it would no longer be unnecessary.
No, the GPL very much requires copyright to work. The whole point is copyleft, which obligates changes to the code remain under the same license and be available to everyone.
Without copyright, companies just wouldn’t share their changes at all. The whole TIVO-ization clause in the GPL v3 would be irrelevant since TIVO can very much take without giving back. Copyright is very much essential to the whole concept of the GPL working.
Just think, why would anyone want to use Linux if Microsoft or Apple could just bake Linux into their offering?
