Bluesky is a for profit venture with a marketing budget it uses to sell the idea the platform is decentralized.
Bluesky is not decentralized and there is no realistic business plan proposed for how to lucratively monetize a truly decentralized network. Bluesky MUST turn a profit, this isn't an inconvenient detail, it is a crisis the company is on the clock to solve like any heavily speculative venture capital funded startup is.
The only way this works is if actual meaningful decentralization is always "on the horizon" for Bluesky as something the for profit company can periodically point to and say "look how close we are!" while never taking meaningful steps closer.
Bluesky silicon valley techbros will point to their cool blogpost about how they set up a hobbyist project on Bluesky outside of the central network and it will remain a pipedream or like the end of a rainbow for 99.9% of us, an impossible promise that flies away as fast away as we chase it.
