But he's not dropping out ! He just decided that in his case, is better to run PRIVATE nodes. That's all. Public routing nodes require a lot of work and resources, things that he reached a limit. You can run perfectly fine a private node (non-routing) and nobody will say absolutely anything and your payments will go through perfectly fine.

What is wrong with that? They respect the main protocol and done. LN is composed in many levels of nodes, not just routing nodes. Decentralization do not come from how many public routing nodes exist, but from how many private nodes are using that public liquidity... I am sure there are more private nodes than public ones.
