Yes the wallet fingerprinting stuff sounded kind of crap/BS. But if you asked them they'd just say "oh yes but our system is much more sophisticated than that; we can't tell you more because it's proprietary". And while *that* is BS, it's also true that the principle of multiplicative/compounding on fingerprinting is unreasonably powerful (see: browser fingerprinting etc.).
I strongly agree that LN is an exceptionally good tool for privacy despite its (imo heavily overblown) limitations. But my general comment was about the "move large amount through anon technique X" and that comment very much applies to LN too.
I guess your "Wasabi is a perfectly good wallet" was more aimed at the article than at my comment about it, but yeah, I agree that this is not evidence against Wasabi's utilty.
