Why are you people shaming people for what they wear?
Imagine if this were an image of a trans woman wearing a beautiful pride rainbow skirt with two muscled pitbulls, all of you would be considered jerks for shitting on her, yet here we are ragging on this dude and his poor taste in jackets.
Ironically, I wish people including yourself knew more about shit like how PiHole/RaspPi simply leverage Unbound, which is not unique to only Pi software or Pi devices. You can do this same thing on any OS that has it installed.
