A lot of companies / startups that weren't legit was using Facebook to promote their product. This misled some people and Facebook decided to take down all crypto related ads.
I think this is a good step because Coinbase is a legit company that provides value. Hopefully Facebook will allow more companies in this space to advertise as long as they are legal / provide an actual service.
I have nothing against advertisements but over the past few months it has become too much. every video or every scroll there is a different commercial , advertisement and people have been very disappointed that this has been only progressing and the number of commercials is only growing. something needs to change
