Personally, I'm currently for short copyright lengths - and industry-dependent, based on independent estimate of true ROI and technology turnover, and balanced against the public good. So e.g. in chemistry/drug manufacturing this could be a decade, in software industry no more than two-three years. Definitely not "almost a century after the death of the author".

I would be a bit conscious about the "sharing without direct monetary gain" part, I'd like it to explicitly exclude "sharing for free in exchange for viewing ads (and accepting tracking)". I think "free with ads" business models are fundamentally anticompetitive and poisonous to our society; you can find them at the center of a lot of problems currently afflicting the western world. I would like to see these business models gone.
