Most of reddit is self-aggrandizing cliques who believe they are much smarter than they really are -- especially in the cryptocurrency space. My concerns are not obscure or unknown, everyone who pays attention knows that Monero has issues.
There are multiple projects that are better in terms of financial privacy -- Monero is primarily an ugly hack to barely obfuscate transactions.
I highly encourage you to visit r/Monero. Those devs are the first to say it isn't perfect. They've never promised the moon or hype themselves. They acknowledge that people's lives could balance on whether or not their finacial transactions are private, so they don't overpromise and always continue to look for ways to improve.
It seems like you have an agenda and a viewpoint that doesn't line up with reality.
(And a lot of people seem to criticize Monero because it's not anonymous (which is not the goal), so that's why I say it isn't perfect. And of course there will always be an attack vector for everything: people could track serial numbers of physical cash, the NSA could track every keystroke/tap on every device, etc, but realistically it's very good and getting better about blockchain analysis attacks.)
I don't have an agenda. My "viewpoint" is reality. You don't have to like it, and feel free to put your trust in technology that does not deliver what you believe it does.
There are much better people to discuss any problems you think it might have over at r/Monero, including people with PhDs (I'll never be as smart or have as much dedication as they do). I suggest using the search function about your concern, and if you don't see it, create a post or make a comment in their Skepticism Sunday threads.
I learned about Monero here on HN years ago, understood its limitations then, and keep mostly up-to-date. I won't claim that any thing in the world won't have its limitations or problems, but I do still believe that Monero is the best project currently and still looks promising going forward in terms of user financial privacy.
