This is the nature of Bitcoiners and some may never be convinced. 
In general, we make products where we minimize the trust required, including designing products for self-custody users.
Whenever we offer a service, some data is always required to provide a useful, tailored service. If you don't trust anyone ever, you will have a hard time and the user experience will be rough.

Over the years I have heard many bitcoiners say that Amboss is collecting data on the Lightning network and node operators and that we should be concerned about Amboss and what they might do with this data or who they are sharing it with.

Why should node operators and bitcoiners trust Amboss and use it products/services?
