He's doing us a favor by not plastering ads all over his site.
It's funny I wonder about the influence of ads too like you by using ad block experience a better internet (no influence on behavior).
There's a hijacking thing too of intent, at which point I modify websites to hide these above the fold attention grabbers.
My kindle forces you to read an ad everytime you turn it on. I know you could root it, lost money on device, etc...
SteamDB looks pretty amazing and sleek without ads. Putting ads would only degrade the user experience and force people to install adblockers or use adblocking browsers like Brave. Kudos to xPaw for keeping his site ad-free for all of us to enjoy.
