Is BlueSky similar to the Fediverse? No.
The Fediverse is owned by the people and communities that use it. A basic server costs $5 a month all inclusive, anyone can make one. It's ad-free, made by volunteers, funded by donations, servers are independent.
BlueSky is a for-profit corporation funded by VC money. Its technical structure makes servers dependent on expensive corporate-run relays. BlueSky's business setup is eerily reminiscent of Ello: https://waxy.org/2024/01/the-quiet-death-of-ellos-big-dreams/
p.s. Some misunderstanding of what is required to start a Fediverse server. You don't need to install software or do anything technical to create a Fedi server.
There are many managed hosting companies that do all tech stuff for you behind the scenes, including updates and maintenance. Using managed hosting is about as difficult as setting up an email account.
I run a website at https://growyourown.services to encourage more non-technical people to try managed hosting.
@FediTips This is actually relates to a blog I'm starting about documentation failure for new users, and knowledge hurtles.
