I use coinos because it makes LN easy for a non tech person like myself and I want to be able to spend sats not just hoard them. It is disappointing that LN seems to lead to increased centralisation of control and even technically competent people like you struggle to manage independent LN liquidity. The protocol and its layers are still evolving and a lot of people contribute in good faith, sometimes at a loss but that is the nature of innovation and ultimately growth. Bitcoin is an experiment- its interesting to see it progress. In a similar way to your experience I struggle to see how my small scale mining will ever break even- its really more of a hobby, learning exercise and interest than a viable commercial investment...and thats ok by me.
