Netflix gets paid to promote content? That doesn't make sense. They buy or license content, and their incentive is to get you to like what they have to offer in order for you to keep paying them a subscription fee. Why would they pay someone for content, only to have them then pay them to promote the content?
"Help me find things I like" is basically a mandatory requirement for anything whose catalog is too large to search exhaustively — otherwise there's no point to them.
Doing this well seems to be surprisingly difficult for everyone. Facebook has shown me local news in Florida even though I'm British, live in Berlin, and have not even visited that state. Twitter thought I was interested in baseball, when I don't care for any spectator sports. YouTube is mostly OK for the long form content, but the shorts are 98% useless, and the adverts are… well, the current ad for me in the app is "Click this video = $1000" ad by "Beast Promo" with a cartoon that looks like MrBeast, which absolutely screams "scam", and last week it was something that looked like an anti-LGBT conspiracy theorist but my German isn't good enough to be totally sure.
Netflix, Disney, and all the rest? IMO Netflix is the best of them, but still not really all that amazing — the bar it passes that the rest fail is excessive focus on their own content.
