A new EU antitrust regulation that targets big tech.
The gatekeepers were given six months to comply with the DMA.
In Apples case, one of the requirements is ending the mandatory 30% fee for in-app purchases.

Spotify haslong ralliedagainst the charge, which the company says it has to pass on to consumers.
Last year, the streaming giant decided that the benefits werent worth the cost.
Spotify announced that it would no longer allow Premium customers to pay for service service through Apples in-app purchases.
With the DMA, however, users will get new options.
We know, pretty nuts, the company said in a Wednesdayblog post.
Thats the plan, at least but its not guaranteed to succeed.
Apple has yet to reveal precisely how it will comply with the DMA.
If recent history is anything to go by, the iPhone-maker will search for ways to circumvent the restrictions.
For now, however, Spotify has reasons to be cheerful and so does the EU.
