Your post seems like F.U.D.

#1: "between 2019 and 2023"

#2: the author wrote "This attack is not realistic. ... This is why everyone needs to run their own node"

#3: "digital forensic approach can still reveal sensitive information by examining off-chain artifacts such as memory and wallet files"

So...

#1 seems to have been mitigated.

#2 seems to not be an issue if you run your own node.

#3 seems to not be an issue if you don't let others do forensic analysis on your own computer (not the Blockchain).

It's good that people do this research to help make Monero better. I am not criticizing the people that published what OP linked to. But of course OP's post is like saying "What makes you think paint is safe? Here's a post about how paint used to include lead."

The fact that it's delisted from most exchanges because of its privacy features; if it was as traceable as Bitcoin, then the feds would allow it. What I see from these links is that it's not fully "traceable" and more educated guessing via heuristics.
