Seeing as RCS with encryption based on the MLS standard hasnt been deployed yet, can you show exactly what metadata is leaking?

Well, instead of leaking metadata to Signal, AWS, Cloudflare, Google/Apple and your ISP, like Signal does, RCS only leaks it to your ISP /s

MLS only deals with encryption and key management, which is great but that's been a "solved" problem since TextSecure (now Signal) introduced the TextSecure Protocol (now the Signal Protocol) in 2013.

What I'm aware is missing with RCS / MLS compared to Signal (someone with more recent knowledge please correct me):

Sealed sender so only the recipient knows who sent the message.
Not storing metadata or logs.
No built in crash reports.
Private contact discovery.
Published government requests providing evidence that they don't have any data.
Open source client.
Looking at the Google Play store, Google's Messenger shares precise location data with third parties, Signal doesn't.
Also on the Google Play store, Google's Messenger app list a lot of data collected. Signal only lists phone number.
