As far as I know Meta only collects and abuses data it get’s from people where there are now laws in place to prevent it (so why wouldn’t they do it).

Unfortunately, in practice, the laws don't seem to mean much to the wealthy.

Like other gigantic companies that have billions of dollars, it's easier and more profitable to ask forgiveness than permission; paying legal fines that are 0.01% of their overall profits is just the cost of doing business. Zuck has been caught on multiple occasions skirting the law (see the most recent revelation of them surreptitiously leeching scores of books from Anna's Archive and a previous one of partnering with Cambridge Analytica, for example).

I'm all good with having companies submit to hostile financial audits, but I'm not sure how a CPA would be qualified to validate security or privacy. Code security audits should be done by cryptographic experts, and I think you would need both.

Perhaps one day, we'll have Certified Public Cryptographers that have a fiduciary duty to ensure people are secure or private.
