Yes, i edited my post since i was thinking out loud at first, sorry. Zero fee routing might not be as centralizing as i thought. But negative fee routing seems like it will. Blockchain analytics could set up nodes with negative fees and have sooo many payments route through them since probably no-one else would have an incentive to do negative fees. But thats off topic.

>which can be centralizing

There is no such thing as "centralizing" in LN. Absolutely anybody can spin up a node and run it with whatever fees and policies.

If you do not want to use those nodes, you simply open channels with other nodes and route and pay without them.

Thanks for sharing. Seems like a good idea at first glance but it seems to favor zero fee routing policies more. But there might not be anything wrong with that.
