I completely agree, I'd fully support copyright being reduced to 25-30 years.

The whole point of copyright is to grant an initial monopoly to a creator so they can benefit from their work, promoting the viability of further creative works. It's supposed to be a positive for the ecosystem as well as just the individual creator but I'd argue absurdly lengthy copyright terms, the fact IP trolls are a viable business model, and the fact large corporations end up dominating the creative space are all ways copyright as it stands negatively effects the overall creative ecosystem. 30 years or about that would permit the creator to benefit exclusively from the original release and a nostalgia cycle, but then it'd be fair game for everyone else to build on which is how culture has always worked. I think that arrangement would be far healthier and promote more creativity.
