If you want to fix copyright, you need to realize it's a complex matter with lots of different actors and conflicting interests. Thus you will need to be able to discuss it accurately, to ensure people aren't getting a mixed message.
So let me help you out with a starter pack of accurate statements.
Copyright is not a fundamental right. It's an artificial monopoly enforced by government based on promises of enriching society at large, by giving it back for free, in the future, after a limited period of exclusivity.
Violating copyright isn't theft. "IP" is a legal construct to make something fundamentally unnatural (owning an idea) seem natural. "IP" is not real property and it cannot be stolen.
Having firmware for stuff you own being copyrighted and implemented in a way which makes it illegal to tamper with is clearly not in spirit with the way copyright law was written nor its intent.
Having copyright last 100s of year in a time where something is obsolete or outdated in less than 5 years is clearly also at odds with "enriching" society. Nothing is being given back. And if it is, it's long past the period in which it would be useful.
If you want to "fix" copyright, we need to get more focus on the spirit and intent of the law, rather than the "right" part of the law and specifically how big corporations look at it like a blanket-right to profit, for all eternity.
