Hijacking these controls as a way to prevent copying/inspecting used to be far more prevalent. For the most part these days it's not done to intentionally interfere with these actions, but rather as a misguided attempt to replace core functionality with something supposedly more "user friendly / beneficial".
The worst offender now is the applying of click event handlers for links that simply navigate to a URL. The inability to open a link in a new tab only because the developer chose to use a <span>/<div>/<li> that triggers a javascript framework routing action, instead of using an <a> tag pointing at that route... sigh.
The vast majority of publishers don't use those tricks.
