Using antidetects for multiple ad accounts?

Some consider antidetects a fraudster tool, yet I found they are widely used for normal business reasons as well, esp by ad and social media people. Amazon earned $40b on ads alone last year - maybe that's one of the reasons they strongly disapprove multiple accounts on their platform.

I always thought Facebook and Meta are in the lead of online safety, esp when their revenue is involved. But it seems like small commercial antidetects somehow seem to stand against big corporation defense lines really well.
