Legalese is the lifeblood of lawyers. I mean any type of lawyer you can think of. Now to answer your question in the context of the music business, well, there is no record company that wants to lose money. The same applies to any music publisher for that matter.
Even if it means screwing recording artists in the process so be it. And that pretty much summarizes the reason why record contracts are deliberately set up in most cases in favor of the investor (i.e. the record company or music publisher).
The idea is to initially trick noobs who are still green in the showbiz industry even to the extent of legal malpractice as I have mentioned above. Hence, it is up to the recording artist to do due diligence and look after their own interests from the first day they are given the offer to have someone go through all the details in the fine print.
Failure to do that an artist will soon find themselves whining and throwing tantrums whilst posting cryptic sosho media posts about X record label and X music distributor. However, record companies are also smart enough to know which artists to try and which artists their dirty business tactics won't fly. So what do they do with the latter?
They sure offer them fair contracts. The end result will be a win-win situation for both parties. By the way, these artists have usually established brands with a proven track record.
