Are you considering running a Bitcoin Knots node? It's certainly your right to do so.
But you should be informed of what you're getting into.

Your critiques of Luke's security and development practices seem legit, but your ad hominems seem uncalled for. I'd say that just like wallets, more node implementation options is better than less. Undoubtedly there will be pros and cons to each implementation but users can decide and competition makes for better products in the end. Personally, I use core for transactions but knots for mining.
