Copyright is abused in may ways that go far beyond perpetually extended copyright protections. The DMCA has enabled copyright to be used as a weapon to silence criticism. Companies have created a revenue stream out of sending DMCA notices demanding that people (innocent or otherwise) pay settlements now or else face long and expensive court battles. Creators are threatened with lawsuits or dragged through the courts on highly questionable copyright grounds just to bankrupt them and prevent them from being a competitor.

Recently, the media industry has taken to suing ISPs for billions if they refuse to permanently stop offering service to customers who have been repeatedly accused of violating copyright. Without any court finding you guilty or any actual proof that a violation took place, if you are accused multiple times and your ISP doesn't disconnect your service forever they could be fined out of existence. Most of the ISPs sued so far have settled out of court, but the media industry has been winning in the courts as well.

Copyright is regularly abused to do things that go far beyond what it was intended to, and often to the determent of the creation of new works. Most of the people hurt by such abuses have no ability to fight it, and very little hope of actually winning even if they try.

Most of the copyrights nowadays are held by large conglomerates anyways and not artists, sure that's not a nuanced point of view but copyright isn't nuanced either

Original copyright terms didn't last for a lifetime, either.
