Removing transparent address support would allow us to compete directly with other top privacy coins like Monero, by making every transaction on the blockchain shielded; by keeping transparent addresses, over 99% of the transactions on Zcash remain non-private, which is really a disservice to the technology and purpose of Zcash. We need to embrace our goals of privacy, unabashedly.
I second this notion.
In general, the points raised in this YouTube channel clearly express the risks to Zcash if it always maintains the Transparent Pools.
In short, privacy advocates don’t like to recommend Zcash over Monero because Privacy is a technical opt-in feature, rather than by default. (Despite acknowledgements that Zcash does have marginally stronger privacy cryptography)
