For products like Google Web Search, we provide a link to the notice as published by Lumen in place of the removed content. Vyper scripts directly compile to EVM bytecode rather than getting interpreted, as with Python. This minimal and clean composition of contracts and enforcing of self-explanatory code patterns also make Vyper appealing to the more conservative Ethereum Classic community and its "code is law" ethos.
