...Decentralized applications are run from source code running on the blockchain network so these applications are not controlled by any individual or organization.
The "decentralized" in Dapps is quite misleading. You could interact with these applications without the need of a middle man but I wouldn't go as far as saying nobody can control them. I am pretty sure you've read about hacked DeFi platforms freezing activities like farming and staking pools.
the weakness of dapps is that, I see many cases that seem to be hacked from dapps security and connect wallets there. this should really be fixed so that users are not under the threat of dapps
