Because when they break things they lose hours of work they cannot afford to lose. My parents had a small business and if my mom mis-clicked somewhere and deleted some important thing, she would enter a panicked rage as she'd lose half the day with some remote tech support. She would never touch a computer after work, because it just stressed her, she found them absolutely unbearable, also because the tech support was unbearably obnoxious.
