The fact that many people couldn't see this, and will defend and simp for orgs like amboss because "ooh muh pretty! I can label my node too!" is part of the reason we need to keep trying harder to educate and build tools to make it easier and more natural to be sovereign. Yes, we want to see the best in people and orgs where we have some agreement. But we should be verifying. And even if you trust some, you still need to follow-up verify. Connect and use tools cautiously. Test things.

What about lightning+ network!!?
Information that is freely gossiped is fair game to the network.
That means the alias you give your node, how many channels, what nodes they are connected to, when they were established, when they close, whether you are running clearnet or only onion.
It's not desirable, but it's a known tradeoff. We SHOULD be pushing for more privacy improvements like that offered in Bolt 12 for some degree of anonymity of payee. Integrating conjoins for pre channel funding, splicing, and post closures would also be nice.
What Amboss is doing goes above and beyond the freely gossiped data. They are an analytics firm, not much different then Chain Analysis and others in the intent to track transfers and attribute to entities. They don't do this purely for their own entertainment or to simply benefit people looking to understand routing. They sell the information and services.
To reiterate... If you are not paying for a service (monetarily, volunteer building, etc), you are the product.
