What has Coinbase, a centralized exchange renowned for being anti-privacy and working with governments and surveillance agencies, selling customer data, got to do with Lightning nodes leaking information about the transactions they are routing? You might as well say that you cannot use Tor nodes because Facebook collect your data. Complete non sequitur.
I personally would prefer multiple different methods of scaling but I am not in charge.
I don't necessarily disagree, but I would worry about splitting the user base across too many solutions. "I want to pay via scaling solution 1" - "Oh sorry, I only accept scaling solution 2, and the other merchant down the street uses scaling solution 3". I agree Lightning is not a holy grail - at least not yet. One of nice things about Lightning though is that different pieces of it can be upgraded or changed individually - see Eltoo for example. I think I'd like to see more people adopting and driving the development of Lightning to make it better before we start introducing additional solutions.
