TBH I prefer ads. As a small business owner, online ads have allowed me to grow my extremely niche business without spending a large bundle of funding, and I'm sure it's helped countless more small businesses compete against the big box stores that can afford to do their own advertising. From a user perspective, the product can be given out for free, which for social media is a must, unless we want to start seeing classest messaging platforms excluding people in countries who can't even afford 1 dollar or make digital payments. If I was going to let ads bother me I'd be much more upset about someone owning my search engine, phone, email, personal documents, cloud storage, etc... who could cross references those sources to build an accurate picture of my identity, rather than someone just owning my social media accounts where I'm just about as fake as necessary to make my grandma think I'm still going to church.
