This is true and it isn't true. It depends on context. What content are you placing? Who needs to see it? What kind of mentality will they be in when they're looking for it? In a rush or browsing? All of these factors will determine what kind of placement is optimal. If you're talking about an info box with a CTA in it, maybe it doesn't need to be near the top of the page or viewable on initial load. But if you're a service based company, and you're talking about a support link, having it anywhere other than prominently displayed immediately on page load is going to aggravate your customers. In that case there is definitely "a fold." The fact that there's 4k different devices viewing your page doesn't change the fact that their browser window has a bottom, it just means that the location of that bottom is volatile. If you really care, your page design can be responsive to not just the width of the browser window but the height as well. Abusing the concept of a fold is lazy and ignorant. It shouldn't be treated like the only aspect of web browsing that matters. But at the same time, ignoring the fact that some of your content will be immediately viewable to users upon loading the page and other content won't, is also lazy and ignorant.
