I thought I will not come back / post anymore on SN, but this question must be answered.

My answer is in my old article I wrote back in May, about the precarious situation of many LN nodes run by noobs, without a base knowledge of how LN works.
I raised from then some alerts to LN nodes runners, devs, users in general.
Some they listen, some not.

Here are my articles and I suggest to all to read them and pay attention to the details:

• Lightning fees experiment
• Recommendations for LN users
• Running 2 types of LN nodes
• Getting started with LN

TLDR:

• many make the confusion between a routing node and a simple LN node. Are not the same.
• from plethora of new Umbrel users that was starting in 2020, many "left the building" because they were opportunists that only want to have "passive income". Slowly they realized that is not the case. Running a good routing node is not for noobs and REQUIRE a lot of knowledge. Knowledge that these opportunists do not have it and also do not have the patience to read and learn. They just want NOW.
• from plethora of RPi nodes, many realized that these toys ARE NOT so good for running a good routing node. This end up in many hardware failures, nodes in limbo, funds in limbo, frustrations etc. Myself I was helping many of these users to recover their nodes. So in time these users were migrating to other types of LN nodes.
