they don't necessarily require ongoing maintenance, it depends how they are coded. some might even say the "correct" way is a non-upgradeable back-end (on-chain solidity contracts) and hash-addressed, ipfs hosted front-end. anyone can then pin the front-end themselves to ensure access or just run the code locally. dapps should rely on centralised, server based components as that mostly defeats the purpose.

uniswap is a good example. when they release an upgrade users must explicitly adopt the new version. in fact uniswap v1 and v2 still see usage despite the release of uniswap v3.
