Crypto is not about privacy originally speaking. It was about commerce and unfortunately it hasn't been successful either. Very few commerce is done through crypto. And not many coins have really created technology to be able to, let say, subscribe to digital services or get credit lines for purchase of goods and services.
Most of the internet business models like advertising (cpm, cpv etc) micropayments, subscription models, or secure transfer of shipping data, or independent escrow services hasn't really been successfully addressed by crypto and their Blockchains.
Yet most crypto people are super focused on trying to make it a tool for off internet models like regular person (not companies) to person transfers which is also irrelevant.
