Like every other search engine, social media platform, etc. ever. Remember when ads on Google were highlighted with a big yellow block? Now they look exactly like regular search results, just with "sponsored" in small text at the top. And my guess is they went with "sponsored" instead of "ad" or some such because for some subset of the population it's probably not even clear that sponsored=paid advertisement.
The infinite growth problem / enshittification of modern capitalism. We will endlessly try to squeeze more blood out of a rock until it crumbles entirely.
It's funny in a way. We talk about how risk averse big companies are compared to smaller, more nimble startups. Yet those same big companies don't seem to be risk averse to making aggressive squeezing changes like these.
