askBeehaw: should copyright even exist at all? and if it should, how long should the ideal term of copyright be?

Copyright should protect the artist, not corporations. But it's become a business, with companies made only for the sole purpose of (sometimes falsely) claim copyright of works.

We can see this with videos being copyright strike when they were making clear use of "fair use", or when some years ago there was an issue with channels about Classical Music having their videos taken down for copyright claim coming from a company that alleged to have the rights over different pieces (not the performances, that are protected by copyright), but the piece itself, from different eras/centuries (20th and 21th century compositions are protected by copyright, 19th, 18th, 17th, 16th and 15th century compositions are not)

There also have been cases of an artist/author losing the right to reproduce their own work after getting out of a contract because the publishing house/music company got full right on their work. Sometimes getting to the point that the artist couldn't perform because the music company had the right to the image of the artist.

So, how can copyright be shaped in a way that upholds the right of the artist, but doesn't allow for any kind of corporative abuse to exist?
