Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

I think for ongoing properties, it could create an interesting competition between different companies/artists, and I'd expect the original creators to fully cash in on "I'm the creator of [whatever], this is the real canon!" in order to keep loyal customers/fans

I fully expect game companies to not like this one bit, because live service games, like World of Warcraft or Fortnite, would, sooner or later, have to release source code in the public domain, allowing anyone to check it, create identical, better or worse clones or, worse, hacking tools that might still work on the more current version.

For stuff like the current offering of Adobe that relies so fucking much on "the cloud", now that would be tricky and another significant battle, as they'd eventually have to give up the code for Illustrator, Photoshop, etc, as well as whatever server software their cloud uses, or point to said cloud's owner. The same would apply for Autodesk, Corel, Microsoft, Apple and Google. Imagine finally having an open source Windows XP! 😆

EDIT: What is a lot more likely to become problematic is server-side bank software and some government software that is used for a country's respective army or intelligence services. Boy, THOSE will definitely fight, or want a very specific clause for their cases, which makes sense.
