This complaint can be valid if a) you're not guilty of the "official reason", or b) competitors are guilty of the same things and are not getting penalized.

Can you show that either is true? Regarding b), there have been many, many articles posted here which show competitors being fined for various rule violations, so concrete examples would be great.

Sure, that's theoretically possible. Since the violations listed by GP:

> EU regulators said X's DSA violations included the deceptive design of its blue checkmark for verified accounts, the lack of transparency of its advertising repository and its failure to provide researchers access to public data.

IMO don't fall under this & you didn't argue that they did, I didn't list this possibility. Which of the listed violations do you think falls under that, and which ones don't?
