True, the closest summary as what parent posted I found at https://www.consilium.europa.eu/en/policies/digital-services... under "The consequences for gatekeepers", a page which is linked from the submission article.

It includes the following section:

    Gatekeepers will not be able to: 
    
        rank their own products or services higher than those of others
        prevent developers from using third-party payment platforms for app sales  
        process users’ personal data for targeted advertising, unless consent is granted
        establish unfair conditions for business users
        pre-install certain software applications or prevent users from easily un-installing them
        restrict business users of platforms
    
    Gatekeepers will have to:
    
        offer more choices, such as the choice of certain software on a user’s operating system
        ensure that unsubscribing from core platform services is as easy as subscribing
        provide information on the number of users that visit their platforms to determine whether the platform can be identified as a gatekeeper
        give business users access to their marketing or advertising performance data on the platform
        inform the European Commission of their acquisitions and mergers
        ensure that the basic functionalities of instant messaging services are interoperable, i.e. enable users to exchange messages, send voice messages or files 
    
    Fair competition of digital services is key to ensure that companies and consumers can all benefit in the same way from digital opportunities. This will also generate more innovation and boost consumer protection.
