Not gonna lie, I'm not sure he's smart enough to do it without getting caught. If he was like a real evil genius, with no moral qualms and the intelligence to match his bank account, he'd have his own team of highly paid, specialized coders that goes in with him whenever he buys a site up to install algorithmic tweaking and privacy invading type administration under the guise of standardizing his digital properties or whatever. Twitter was basically a respected news media platform; He could've been tweaking trends to manufacture consent for obscene levels of profit making on the stock market, monitoring DMs for business secrets, elevating his status to that of an untouchable business magnate. Instead he fired everybody off and made some h1b visa slaves platform his meme posts. Maybe he's spying on Grimes, but he's so sloppy, that I feel like if it was en-masse I think we woulda heard about it by now.
