This statement is false. Not all lightweight wallets (wallets that function without needing to download the blockchain) are SPV wallets. Some lightweight wallets use blockchain APIs (and therefore are immune to this problem)

Downloading the full blockhain is not the only way to secure bitcoin.

What doest that even mean?

You mean blockchain.info API? Well Blockchain.info is not immune to this problem, they were running an old bitcoin core version.
