It's a neat theory, but Apple was 4% of Twitter's Q1 ad revenue. I don't think the My Pillow guy has $100M to spend on anything, let alone Twitter ads.
Crypto scams and fake nutrition pills aren't the top advertisements on Infowars because Alex Jones knows more about the media business than Fox or CNN. They're the top advertisements on Infowars because mainstream advertisers won't touch Jones with a ten foot pole.
Same goes for the Twitter that Musk built.
