I only see the fact that despite many complaints about CEXs, its user base is still overwhelming compared to DEX. This shows that the security advantages of DEX are not yet better than its limitations.
People forget if ED and FD were the best DEXs so far with a very good security. All of DEXs other than it just sell the name of dex to gain popularity. As OP said above if even binance dex was one of the worst dex or i could say if that was a fake dex.
