Only two things come to mind:

1. Provide or find pro bono legal resources deeply familiar with EU DMA and similar antitrust regulations, willing to proof-check and improve this report, and perhaps advise on better channels to submit it.

2. Locate more affected end-users, including applicable members of the GrapheneOS Foundation and developers behind other distributions, make them aware of these efforts so that hopefully we submit a joint complaint. (Might get more traction, though AFAICT reporting is limited to EU citizens).

Happy to fork this into its own repository if it helps with collaboration.
