...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.
I expect the term that cant controlled by any individual or organization is that if the dApps already deployed, the code cant be changed anymore.
Its not like an traditional apps where someone could update the apps and inject virus on it.
