Right - it makes you smile! And a dark kitchen makes me depressed. Why shouldn't we both have what we want?
Sure, white boxy houses might be boring, but considering the many, many problems we have going on (mass shootings, racism, wealth inequality), how big of a problem is it really? And when you think about how many people are leaving everything they have and literally running for their lives around the world, and those who live in servitude, utter poverty, and endure a lifetime of back breaking labor, is an overabundance of shiplap such a big deal?
I think these trends are really most obvious in articles or websites because they have to do what is trendy. We've been house shopping recently and I haven't seen a single shiplap wall or treatment. Although I have seen several hideous slabs of cheap gray granite. Blegh.
Now, don't be mad, but I actually bought some shiplap last year. During our kitchen reno we moved cabinets and that left some unsightly walls. It's really expensive to have them retextured and I don't like wall tile with formica (which is what we put in, I actually like formica). I thought shiplap would be a good way to go but I was worried about dust collecting in the grooves and never actually put it up. We just painted over the unsightly walls with flat paint and they pretty much just blend into the background. When we sell, I'll probably use some of it. It's cheap, it's easy to do, it can be painted any color you want, and if new buyers hate it, they can just take it out. I see a lot of houses with ugly, dated tile that would be a nightmare to take out. I think shiplap kind of serves the same purpose that tile and wallpaper used to, but it's easier and cheaper to do. And probably somewhere in the middle, waste-wise. More waste than wallpaper but much less than tile. And apparently wall paper requires a totally flat wall, so that's pretty much off-limits for older houses.
As a conciliatory offering here is my version of a lovely craftsman bungalow (you'll probably hate it because everything is painted, but all the beautiful details are still intact!):
