I think twitter can not do the same even if they want to. Users can only advertise bitcoin but twitter as a whole I think is impossible. Twitter supports strong blockchain. Maybe one day twitter will switch to blockchain technology in running the project. I also believe that if twitter has adopted blockchain technology it will most likely also create an electronic money currency for use on twitter. If Twitter decides against crypto, it will affect the cryptographic community very badly. It has also been the means for celebrities to share their encrypted investments with their fans. They are struggling with their own development and therefore can not make such harsh steps.
