Why does an individual utilize the conjoin/collaborative spends?

What is the purpose of using this privacy tech?

Imo it's an attempt to obscure the history of UTXOs. And there are varying reasons for this. Not all are nefarious or, would be deemed illegal by state/country governments.

This implementation literally checks the UTXOs (against what 'list') before permitting them to enter.

Now you guys as a company. Assuming your with trezor from your posts and defense of this, you guys have every right to do as you see fit. But the way this is portrayed as some optimal conjoining schema.

It's not imo.

Just as you guys have the right to do as you see fit. I have the same right to call it out.
