EU commission designates Booking.com as a digital gatekeeper under DMA

The same announcement from their own website: <a href="https:&#x2F;&#x2F;social.network.europa.eu&#x2F;@EU_Commission&#x2F;112434381586334896" rel="nofollow">https:&#x2F;&#x2F;social.network.europa.eu&#x2F;@EU_Commission&#x2F;112434381586...</a>

Is this Europe&#x27;s first home grown digital gatekeeper?

I didn&#x27;t see any comments on implications. Can anyone TLDR?
