They're tanking search results for users ON A PC OR LAPTOP due to your mobile-friendliness. It's bullshit and it's forcing the internet to make an unnecessary change and waste money and/or time because they think the web should be more mobile-friendly. It's corrupt, stupid, unfair nonsense and the FTC, FCC, or Supreme Court will crush them when someone eventually files suit over this.
Personally, my business opinion of my computer repair company's website is if they can't read it on a smartphone very well, use a real computer. I chose to completely ignore mobile-friendliness (although my site is extremely fast loading and uses simplistic HTML and no plugins so it actually is mobile friendly, but not in Google's opinion) and now I'm getting penalized by Google for users who are doing the right thing and using a real computer to do searches instead of an inadequately fast device with a 4 inch screen.
