My criticism of blockchain is how niche the uses are. Bitcoin is great, worldwide transactions that are immune from the US government printing money every year. I understand that. Voting and timestamps, great uses for blockchain. However more complex work may need significantly more oversight. Sure its not great to add columns to a database, but you are not going to have this ability if millions of people dont need the columns. Thats the fault of decentralized chains. Centralized blockchains defeat the purpose obv, but that hasnt stopped hundreds of coins from doing this. Im very skeptical of crypto outside of bitcoin.
