Firstly, they can't exist most of the time you can't actually call a lawyer and talk to them - you get their office and their "job" is to gatekeep that lawyer from making any discussions with anyone who isn't represented or paid for a consultation.

Secondly, once you do get into contact with them you'll get a blank stare or phone silence. This is not how most lawyers view pro-bono work. Most of them have a very small quota of pro-bono work to be done and that's it. They get assigned a case by their firm or go and accept a few a year from the state and they're done with it. The idea that an altruistic lawyer exists out there ready to do free and unpaid work is virtually non-existent today.

Big money interests rub shoulders with US politicians, US politicians deal with their overseas counterparts. Therefore, big enough DMCA requests will be mentioned behind closed doors in the same breath as international trade and other geopolitical concerns. Money protects money in deals between close enough friends and allies.

If Codeberg were based in Russia or a US geopolitical adversary, on the other hand, such requests would likely be ignored.
