On an ad-supported site, you're not the customer. The advertiser is the customer, you're the product. Making that even worse is social media, where being good on a technical level is only meaningful when we're talking about handling scale -- the rest is if people you care about are using the platform.

If you want to see how bad it gets, look at how Facebook abuses CSS in order to have sponsored posts say "Sponsored" at the top while avoiding a straightforward place in the generated html that says "Sponsored" and could be matched by adblockers. It's nightmarish.
