The EU’s latest crackdown on big tech is taking shape. The bloc yesterday released a list of companies they must adhere to the strictest rules of the historic Digital Services Act (DSA).

The 17 platforms and two search engines reach at least 45 million monthly active users. They all have four months to meet the full obligations of the DSA.

The services are now tasked with mitigating their system risks and putting robust content moderation in place (meaning you, Elon). They range from banning ads targeting sensitive user data to special risk assessments for mental health impacts. vviolations can be punished with fines of up to 6% of a company’s global turnover.

According to the EU, the new rules are designed to empower and protect people online.

“The whole logic of our rules is to ensure that technology serves the people and the societies we live in, not the other way around,” said Margrethe Vestager, Executive Vice-President for a Europe Fit for the Digital Age.

“The Digital Services Act will bring meaningful transparency and accountability to platforms and search engines and give consumers more control over their online lives. The appointments made today are a huge step forward in making that happen.”

These are the 19 services that have been designated:

The online platforms:

• Alibaba-AliExpress
• Amazon store
• Apple App Store
• Booking. com
• Facebook
• Google Play
• Google Maps
• Google Shopping
• Instagram
• LinkedIn
• pinterest
• snapchat
• TikTok
• Twitter
• Wikipedia
• YouTube
• Zalando

The search engines:

The rulings are another milestone in the EU’s mission to lead the world in technical regulation. However, that doesn’t mean the union is above the moment with a cringe-worthy pun.

“Today is D(SA) Digital Regulation Day,” said Internal Market Commissioner Thierry Breton. “The countdown has begun for 19 very large online platforms and search engines to fully comply with the special obligations imposed on them by the Digital Services Act.”

Over to you tech barons.
