I have an easier time understanding a subscription-model social network to help weed out trolls and bots, but subscribe just to search to get rid of the ads...?

I have an easier time understanding a subscription-model social network to help weed out trolls and bots, but subscribe just to search to get rid of the ads...? I mean, even if DuckDuckGo didn't exist, this would strike me as a funny concept. Also, I see they want to "personalize" my experience. So they want to harvest search patterns and figure out my personal life as usual? Besides the questionable ethics here, I'm not even convinced filter bubbles are a good way to reach objective information, and you'd think this would be sort of a technological goal for year 2021 onwards, given what took place in 2020.
