I found this article to be poorly-written and deliberately inflammatory. I'll gloss over the regular criticism of "stop conflating cryptocurrencies with blockchains".
It makes continual leaps from Satoshi Nakamoto's intentions to short-comings of non-BTC cryptocurrencies, and then snowballs this into the tremendously non-sequitur subheading Bitcoin has failed. Cryptocurrencies and DeFi platforms are now more vulnerable to privacy breaches and hacking than traditional banking.
Personally, all I see are a string of obvious scams collapsing. These scams were perpetrated by imposters pretending to be a part of a movement so that they could better tug on their victims' heartstrings. But I fail to see how the goals of these imposters should be conflated with the intentions of Satoshi Nakamoto, purely because the imposters bastardized Nakamoto's tech.
Also - the title is barely the subject of the article, but even if it were, I don't think that it, in any way, stands contrary to the goals of Bitcoin. I could see it being an issue for a blockchain meant for privacy, like Monero, but I didn't see any such reference in the article.
