EUの戦略については、こちらにプレスリリースがあります。解説するニュースも出ると思いますが、まずはソースにあたってみましょう。

EDPS launches pilot phase of two social media platforms

以下は私の解釈です。

EUは、EU以外が提供するプラットフォームに依存して情報発信をしていては独立性が確保できないため、自らの手で発信しようとしています。

そして、広告をはさまず、個人情報を解析させない、プライバシーとデータを保護する代替のソーシャルメディアを提供しようとしています。

この役割を果たすものとして、今回はマストドン（Mastodon）とPeerTubeが選ばれたようです。

マストドンはTwitterの代替、PeerTubeはYouTubeの代替となるシステムです。

いずれも、ActivityPubと呼ばれる、SNSをWebのような分散型で実現するプロトコルに基づいて設計された、実績のある仕組みです。

There is news that the EU has set up a Mastodon server. PeerTube has also been set up for video streaming.

It may look like they are trying to gather people and turn it into a platform, but that is not what this is about.

This is the establishment of a server for official announcements and information dissemination, which ordinary users cannot register.

The merit of this system is that organizations and individuals who disseminate information can send out official content on their own.

They can own and disseminate content with their own responsibility and authority, rather than having to look at the platform's face.

It is a natural choice for governments and administrative agencies to operate Mastodon on their own.

We, the general users or citizens, can create our own accounts in any location, follow the services of servers that provide public services, and see what is retweeted.

We just need to make sure that it is a real source and not an official mark that Twitter puts on it.

This means that not only governments, but also news media, artists, etc., do not need to be bound to a platform in order to own their own content and share it with the world.

They can prove their authenticity because they are transmitted from their own servers and cannot be erased without their permission.

However, no matter how reasonable this system is, everyone is using Twitter, Facebook, and YouTube nowadays, so the only option is to transmit to them.

Therefore, the fact that a large organization like the EU is starting to communicate in this way could be a trigger and a big push to change the world.

Coincidentally, we are witnessing a major change with the acquisition of Twitter.

Is it right that both the state and the media are dependent on a private company, much less a privately held company run by a major shareholder? What can we do?

Well, it may not work.
But it should give us some food for thought.

For more information on the EU's strategy, there is a press release here. I'm sure there will be news that explains it, but let's hit the source first.

Here is my interpretation

The EU is trying to do it on its own because it cannot ensure its independence if it relies on platforms provided by other countries.

It is also trying to provide an alternative social media platform that protects privacy and data, without advertising and without allowing personal information to be analyzed.

Mastodon and PeerTube seem to have been chosen to fill this role.

Mastodon is an alternative to Twitter and PeerTube is an alternative to YouTube.

Both are proven systems designed based on ActivityPub, a protocol for realizing SNS in a distributed, Web-like manner.

@noellabo ダジャレを検出しました（検出ワード: コッカ）

@noellabo コロナは世界往来のリスクを、中国の香港政策は工業の一国依存のリスクを、ロシアの行動はエネルギーの一極依存のリスクを、マスク氏の買収騒ぎはITの一社依存のリスクを世界に教えた。グローバル化の流れは既に反転し分裂（分散）の時代になったことが示唆されます。

@sn_twoo_zn そうだねえ。

そういうことが、なんとなく伝わるといいのだけど。

@noellabo でも、政府の管理により各国ごとの規制が強化される方向にもなります（各政府の動機はそこにある）。結果、規制強化により現世代のプラットフォームは衰退します。もとより未来は、今のネットの延長ではなく、新しい「なにか」になります。その端緒となるでしょう。もしその「なにか」を構想できれば、すばらしいことです。
