Lol...never going to happen.

Data saver is garbage.

Google insisting that devs make everything compatible their amp servers so that Google can see everything you do, that's never going to happen.

Making Google the relay for everything that goes through your phone, never going to happen.

You can stop flogging that data saver dead horse. Nostr will never be a Google data collection service.
