What do individuals imply by “L2’s inherit the safety and decentralization of Ethereum”? : ethereum

After I go to L2 Beat and search for L2’s I see plenty of threat round centralization.

Arbitrum’s riks.

Funds could be stolen if

1. a contract receives a malicious code improve. There is no such thing as a delay on code upgrades (CRITICAL).

These addresses are the members of the 4/6 Arbitrum MultiSig.

Optimism’s Dangers.

1. the centralized validator goes down. Customers can not produce blocks themselves and exiting the system requires new block manufacturing (CRITICAL).

Funds could be stolen if

1. an invalid state root is submitted to the system (CRITICAL),

2. a contract receives a malicious code improve. There is no such thing as a delay on code upgrades (CRITICAL).

Dxdy’s Dangers.

Like these L2’s Do not inherit nor the safety, nor the decentralization of Eth, if I take advantage of them, I am being uncovered to smartcontract’s safety, and the decentralization is often on a 4/6 multisig, during which the crew has a few the signatures.

I perceive that these are tasks within the making, and you may’t count on perfection of a mission that’s not function full.

However Being sincere does this phrase (“L2’s inherit the safety and decentralization of Ethereum”) even is smart?

Am I not safer in the intervening time utilizing a good previous and safe trade moderately than an L2?
