Linux is not making anything less secure than other OSs.
In fact it even gives the user more security tools.
So I fail to reason on you singling out Linux here.
Take for example iOS and Android. All apps are sandboxed by default. You can't make a program that just steals all of your credentials like you can on desktop Linux. Having security tools means nothing if they aren't being used.
