Proton built Proton Meet to escape the CLOUD Act. They built it on CLOUD Act infrastructure. Their website promises "not even government agencies" can access your calls. The company routing them hands your call records to the government when asked. Proton hid them from their privacy policy.
To summarise. The data is routed over US services, but its encrypted as they said. This means meta data is open, but the content is not.
Call info is encrypted but Metadata is not, yes. Not really a great “US Independent” solution tho
Agreed
