Perhaps they really know that they will be put in the spotlight if they wanted to go by that route. But assuming they continue to ban it today, then they are the one who are going to suffer the consequences of such bans and not the crypto industry and we can continue to move forward without influencers using their social media platform.
Unfortunately, they wanted to go and join crypto sphere as well with their Libra coin and working very hard to look like they are pro crypto after all.
They don't need that anymore although it contributes but their fame already made them more attractive and if you can see the libra got the spotlight since its been on the topic for several months and since it related to facebook for sure many big whales are into it.
but I since they join the atmosphere for sure the crypto banning will be lift in future since libra needs other alts to became more establish well.
