Ya for sure. I was a Googler so my examples were biased, these aren't the only ad formats that work but there are fewer than most people (even in ad tech) realize.
Yep, even FB "audience network" ads suck and are fraud ridden. Newsfeed is a fundamentally great format for ads.
However I have not logged into FB in six months because the actual content in my newsfeed is so toxic. I wonder if this will cause things to change, although it seems unlikely.
I last logged into FB in 2017... never going back.
