Why breaking into someone's home?
See, since I'm your buddy, you tell me bits and pieces of the stories you're writing for fun. And I, a Hollywood mogul, take those ideas, hand them off to a development crew and put out a movie based on your ideas. You get nothing.
This is normal in Hollywood. Also, I underpay my development crew because capitalism. They hate me but my stockholders think I'm okay. Original content creators like you? Well, there's a reason the writers are on strike, since screenwriting pays so poorly it's downgraded to hobby.
It's a problem especially in the record labels, in which most artists have their content signed away for a pittance because that was the only way to get heard which is changing through the internet, which is why the RIAA is eager to speed up enshittification of social media. And there are some interesting conspiracy theories about why Kim Dotcom was arrested in 2012 days before he rolled out a new music distro system that had dozens of major Hip Hop artists involved that allowed artists to get music out for free and then keep all their touring proceeds. But that died with the Megaupload seizure. Remember that?
If you really want to shill for folks like Disney and Sony and Time Warner, feel free, but you can expect your content to enshittify as well (as it has been for years now). I'm sure Fast and Furious XIII will be awesome.
