Yes! Youtube ads have at least doubled in frequency and intrusiveness.

I returned to twitter after over a year, so I could see some links on a few email newsletters I get. Lots and lots more ads, mostly video, and mostly from what look like ChatGPT-generated company names: Dulale, Tuzely, Lucazoo, Lureza, Beitro, Keybla, Starcess. I see the exact same video posted by multiple "companies". How do I know? I make a habit of blocking all Twitter ads. If I see the same video, it's from a different "company".
