Thank you very much for your input! Would you please publish a proper paper with references to code of the project that proves your statements, that would be incredibly helpful. Also it would be of great importance to backup your words with some facts!
The "fraud" claim is kind of bizarre to me, but it's clear (and not hidden) that Taler intentionally provided less privacy for payees than other designs and systems because of a conscious decision that payees should have less privacy.
I find this objectionable, but not at all deceptive or manipulative.
