Yep. This has been the talk between smaller teams for a while now. I would imagine most of us starting to close nodes after a couple more chains are onboarded. We have to cover up to 10k monthly just in salaries from our own money for a while now. Let alone server and other running costs. I would imagine that at this rate, most small validators, operate at between 50 - 80% loss. For example onboarding stride next is going to send us to -90%. I also didnt notice the concern that general security will, and is already, going down. To save costs, validators will first of all cut server costs, then team costs. This of course, is also a huge security issue.
PS. thanks for the analysis
