Is Warner & other record labels commiting illegal business practices that they should be prosecuted and/or sued for by the music artists on their label(s) as well authorities regulating against trusts and monopolies?

For example I noticed some bands that were on independent labels apparently must have had Warner buy out their labels they were on. The problem with this is, sometimes when some giant sized media companies like Warner for example buys out smaller companies, they shut they independent label down and they also refuse to market the music artists that was on those labels to the public. Why do these giant sized companies do this? To shut down competition that’s been competition there commercial bubble-gum sellout fluff.
One thing they even do is refuse to allow videos whether it’s the regular videos or homemade videos of independent artists exist on You Tube.

Is this not illegal business practices, that the independent artists on the independent labels that Warner and giant companies like them bought out – should be able to sue Warner and other big companies like them for not honoring contractual obligations and be able to get those giant record companies prosecuted for doing such things?
Breezy, if that means bands are getting ready to sue Warner and other giant labels soon – I sure hope so. The bad and exploitive things they’ve been doing to bands has gone on wayyy too long.
On the other hand, these companies have been doing this for a long time and getting away with it because the government’s deliberately turned a blind eye.

Expect to see several lawsuits soon.
