Not pedantic at all. Google lied about RCS being an open standard.
The pedantic point would be saying that RCS, the protocol, is technically open, but the specific implementation that Google is pushing and being adopted is proprietary 🤓
So yeah. Totally fair point and fuck Google for their RCS bait-and-switch.
That’s actually a good point too: Vaultwarden is fully open source. The official Bitwarden server also has proprietary components.
