Get your facts straight. You can blame me all you want, but this is a complete misunderstanding of how Lightning works. If the LSP knows the destination node, it knows the destination. period. And you don't understand how Phoenix works - they don't do source routing. They use they LSP as a trampoline nodes. They construct the path and they know the destination. Moreover, even in cases of source routing - if the user is connected to a single LSP - the LSP effectively controls the path because the graph information is fed by the LSP...

And if you are referring to in-Spark transactions, the same issue exists in an in-LSP transaction... I.e. the sender and receiver are connected to the same LSP.

I recommended you a few times in the past not to overhype the privacy state of Lightning. I suggest you align your documentation with this:
