I think it still requires some cross-over time to make that distinction. It's probably a 'big decision' to change social media for businesses and will undoubtedly take time,... And for individuals the Fediverse (however improved it's gotten already) still is a higher tech-difficulty than twitter. Plus the choice between servers (even though a feature) also discourages many too as they don't know what to choose or hold off until the right instance comes along. I myself had been planning to transfer to the Fediverse for a few years already, but it eventually took Facebook banning me for a hack on my account, with no supportline or real working contact what-so-ever to eventually get me to do the effort. Lost 14 years of journaling my life there in 4 minutes time... 😕
