To move away from the corporate "socials" like Insta, Youtube, X/Twitter etc to decentralised social networks - mainly the #Fediverse - the challenges not only include the provisioning of the tech. Indeed, people like @elena do a great job to show how nice the #Fediverse is, and how #selfhosting is fun and doable.
That said, the barriers to entry for people are largely cultural: the decentralised nature makes it hard for people to choose one of the thousands of servers, of Mastodon, PixelFed, etc Starting at https://joinfediverse.wiki isn't an entry point for everyone. (however great resource it is!)
Moving from the corporate socials to the fedi, many people need help. Fortunately collective actions like #MakeSocialsSocialAgain in NL, #SaveSocial and #DIdays in DE, #VamonosJuntas in ES, #LeaveX in FR etc help mobilise people to make the change together. That's necessary to overcome network effects and (re)connect through our networks.
Transitioning from their tech to #ourtech
