I have good news for you: Taproot does not enable monero-like privacy
features any moreso than already exist in Bitcoin today. At its core,
taproot is a way to make transactions with embedded smart contracts less
expensive, done so in a manner that may marginally improve privacy
dependent on user behavior (but not in the monero-like way you mention).
For example, it makes it possible for lightning channels to look
structurally similar to single key wallets, but it does nothing inherently
to obfuscate the transaction graph as in monero.

Such "monero-like" transaction graph obfuscation may already exist in
Bitcoin via other techniques (coinjoin, payjoin, coinswap, lightning, etc)
with or without Taproot, so the point is further moot.

Do you have a source on your reporting?

You may wish to rescind your nack.
