Ads are successful everywhere. The size of facebook's userbase helped its ads reach a lot of people, but the number of facebook users has been declining while the old folks staying on the platform grow ever closer to death.

Facebook has done nothing but demonstrate that it's a company which doesn't care at all about its users and is willing to hurt them. Anyone still using facebook at this point is pretty much asking to be taken advantage of and abused. I rally can't feel bad for them anymore.

I still find it wild that Instagram does not share ad revenue with creators. Post something there that goes viral? You'll get nothing by default. (Of course, you could set up ad deals etc etc etc, if canny could could make money from it ultimately, but from all that traffic and all those ad dollars Instagram gets from it, you'll not get a cent.)

> why are ads so so sucessful on meta platform

Because you look at them. Get off their platforms.
