What is Bluesky doing which others can’t do?

A leaf, blueskies and clouds

Following Twitter’s CEO Jack Dorsey’s discussion about de-platforming Trump, there was mention about Decentralisating twitter and BlueSky.

He first made mention of this in 2019 in a number of tweets.

Researchers involved with bluesky reveal to TechCrunch an initiative still in its earliest stages that could fundamentally shift the power dynamics of the social web.

Bluesky is aiming to build a “durable” web standard that will ultimately ensure that platforms like Twitter have less centralized responsibility in deciding which users and communities have a voice on the internet. While this could protect speech from marginalized groups, it may also upend modern moderation techniques and efforts to prevent online radicalization.

When I first heard about Bluesky there was little information then at some point during the pandemic I heard about the iOS only app Planetary. My instant thought was oh no there going to try and bypass all the excellent work which has been done by others already. Especially with ActivityPub now a W3C recommendation.

I looked beyond the Techcrunch post (which is full of little odd bits) to see what I could dig up about Bluesky. Looking at the Github repo from Planetary it seems to be based on the Scuttlebot.io protocol? Its good to also see Scuttlebug to ActivityPub and RSS too. As its Scuttlebot, theres other clients for many other platforms.

So my question is what difference does it make over what already exists?
I get if twitter was to be a client of the protocol that would be generally a good thing and I imagine the publicity for decentralised systems would be welcomed but beyond that? Will their business model change? Will anything change? I guess does anything need to change from Twitter’s point of view?
On top of this all, will all the efforts before hand be forgotten now Twitter throws their hat into the ring? That would be awful for all the hard work others have put in for years and years.
