There is desperate lack of genuine criticism even here at the forum because most of the older members wearing the sigs aren't discussing technical details but just commenting on the validity of LN at all times.
The forum doesn't enforce conformity. On social media platforms if you express the right opinions and cater to specific echo chambers, you get followers and build visibility as a reward. You delude yourself into believing you are leading thought, when in reality you are just a slave to the opinions of your followers, who will destroy you without mercy the moment you deviate from allowed thought. On the forum your opinions are always visible to readers. You don't need to have users on the forum following you to see your posts, much to the dismay of everyone if what you post is nonsense. Now internet communities trend more towards self-censoring filter bubbles, with people getting even crazier and intolerant of each other because they've gotten so used to being around like-minded folks that different opinions are especially more offensive and egregious than before.
LN is technically impressive, but its success depends on people seeing Bitcoin as cash, which nobody seems to want to do because Bitcoin is just perceived as a tool for speculative investment. There was a period where if LN was ready and practical, maybe around 2014, momentum could have picked up to have LN succeed in payments largely due to the Bitcoin community at the time being much more supportive of spending Bitcoin and companies being interested and open. But since then the community has become way too greedy to be able to create an actual Bitcoin economy.
