It’s not unreasonable though that they have wanted to make sure their system of federation etc works well before they open it up, and that that has taken some time.
Yeah it must take a ton of work to make function properly but at the same time, I also think it isn’t unreasonable to doubt that a for-profit entity is ever going to willingly open up their system.
Why wouldn’t they just keep coming up with excuses for why it hasn’t been implemented yet? There is no real genuine promise here like there would be if the federation system was implemented from the start (even if it was janky) and every day that goes by the likelihood that federation/decentralization will ever happen on Bluesky becomes less and less likely.
This reminds me of an early access game selling itself on a vision of what the game will become while clearly having very little intention of ever getting there. They spend a lot of time talking about all the great features they will add like NPCs and quests but are they actually ever going to tackle the tough problems of implementing those features? Or are they just going to focus on selling character and weapon skins through loot boxes?
