That’s great in theory, but not everyone (like children and the non-technical) will understand the full implications of what sharing too much information can result in (like identity theft, targeted harassment, stalking, misinformation campaigns, etc).

No one chooses to “productize”/ commodify themselves for the benefit of Meta (as opposed to when people do so for their own benefit, e.g. streamers), but people have been forced to accept being commodified by large companies as a prerequisite to accessing online social spaces, and that’s bad.
