Sparrow doesn't have any privacy compared to Wasabi or Bitcoin Core:

• Wasabi uses BIP157/158 compact block filters for lightweight private sync
• Bitcoin Core is a full node that downloads every block for full privacy
• Sparrow sends all of your wallet's transaction history to third party data harvesting servers

There's fake self-joins, all kinds of stuff there.

Fake self joins are a waste of block space that provides no additional privacy: https://x.com/Kruwed/status/1978678781188481243

Why wouldn't you do an actual coinjoin instead of a fake coinjoin?
