The horde of authoritarian control wants nothing more than "perfect security" because it means they will have absolute power over what you can or cannot do. This "safe languages" movement is nothing but another extension of that. They'll use the same argument as done with terrorism, drugs, and porn to ban anything that could possibly be used to rebel.
Do you want every fucking aspect of your life paternalistically controlled by some faceless entity which you can't influence? Do you want to live like a machine, always complying and blissfully content to consume whatever rubbish keeps you in a semi-sentient state, while being exploited, monitored, and monetised? That's where things are going, and you don't agree, you must resist before it's too late.
"Those who give up freedom for security deserve neither."
