In the case of copyright, at least nominally, it's the more-restrictive (and European) Berne Convention (1886) terms which have been adopted elsewhere.
To what extent this reflects European rather than US interests I'm uncertain, though the latter certainly exist.
It reflects the interests of special interest copyright groups who work both to get these treaties written with terms favorable to themselves, and to get laws passed to enforce them.
When those laws are passed they try to get the laws to be stronger than the treaty. Thereby leading to differences in laws and a push for a new treaty to "harmonize" different copyright regimes. Strangely, the new treaty harmonizes on the strong end of the laws passed, thereby creating a ratchet effect.
After decades of success on things like copyright terms, Disney finally reached the end of the road when the Trans-Pacific Partnership Agreement died. As a result Steamboat Willie, written in 1924, will become public domain in 2024, some 68 years after it was originally supposed to do so.
Point being that the initial push in the present direction came from Europe in the 19th century, no matter how influential the 20th century US publishing sector eventually became.
And to be clear, I don't think the "US, no, Europe" blame game accomplishes or illuminates much. Far more useful is to note that monopoly power seeks to extend itself, regardless of origin.
I was in Morocco when we signed copyright restrictions, and I can assure you 95% of the pressure is from United States, and it is in the interests mainly of the US and it's allies.
As far as it reflecting European interests, the Berne convention is against European interests as it pertains to US copyrighted work as it offers them less protection than US works and forces a higher standard for US copyright than domestic copyright in many cases.
Understood and accurate so far as I'm aware. As my other response notes, the tradition of copyright maximalisation began in Europe in the 19th century before being adopted by US interests in the 20th. Nationalistic attribution of traits answers far less than monopolistic power expansion.
I agree wholeheartedly, the tradition of copyright maximization has its origins in capitalism and value extraction, as such it follows the siege of global capitalism as that is where the interests in the commodification and extraction of value from intellectual property originates from. So it naturally began in Europe, then in the US, and maybe shortly in China? We will see.
To what extent this reflects European rather than US interests I'm uncertain, though the latter certainly exist.
