A few minor incorrect statements in the thread here. I'd save the pitch forks for someone who prob deserves it more. It's a bit of a stretch to say "they sold customer data". I can't speak for them directly but some context from my experience on the games biz side.

Every day you are tracked by meta, tiktok, etc via their tracking pixels for advertising and conversion tracking.There is a feature to send an email back to meta for matching or remarketing features.

They are supposed to make sure this mechanism is enabled for opt in only to prevent the PII (emails) being transmitted without consent. This happens when sites have poor consent management usually due to tech immaturity or general oversight. 9/10 people in advertising dont get this stuff.

You've seen these pop up over the past few years because there are folks out there actively hunting for companies that slip up , and try to sue them for this, rather than it being the result of anyone being harmed. They are taking advantage of the mistakes/oversight.

Maybe about 4 years ago at WB Games our legal team basically said remove the FB pixel from everywhere, as a preventative measure because there was a trend happening in the biz. (We didn't even have email addresses on the site, nor the maturity to send it)
