There's an email address at the bottom of https://social-data-science-alliance.org in case you want to give them feedback to explain Fedi, interoperability and failures of antitrust legislation/institutions. Some of the participants - https://social-data-science-alliance.org/supporters - might be on Fedi for a public conversation.
However, their aim does seem to be Very Large Online Platforms (#VLOPs) specifically, by definition: https://social-data-science-alliance.org/constitution - non-VLOPs appear to be off-topic.
