> Developers accustomed to language-specific dependency managers like npm or pip find it hard to grasp that for C++, the system's package manager (apt, dnf, brew) is the idiomatic way to handle dependencies.

This is a strawman argument. Just because pip and npm are a mess and security liabilities does not make the c++ situation less bad. A fair comparison would be for languages that got their act together and use cargo, maven or nuget.

Linus is also not alone with his opinion in favouring Rust over C++. I would be hard pressed to use his persona in a negative case.
