Having worked Help Desk for a long, long time, I assure you that your experience is most likely not true for the overwhelming population of average users. The number of times the problem description started with "I just downloaded a free wallpaper..." is obscene.

I never get these calls on cellphones, because the app store does stop the overwhelming majority of this malware. 

 to which of the three lines are you referring tho 

 halp @noBody𓅦🧱  

 I think the third 

 The vital role. I believe, genuinely, that for the majority of users, it does serve a vital role. 

 maybe idk what "malicious" means then 

i just do not believe in the distinction between rogue and non-rogue malicious apps/devs 

 It’s a fuzzy line to be sure.
