I started using Construct 2 a few months ago. I've played around with other game creation tools and experienced their native exporting to various platforms so I'll admit that I was pretty taken aback when I discovered that C2's exporting requires a bit of a runaround. But I didn't let it bother me, because I found that the tool itself was pretty darn good and was exactly what I've been looking for (basically an alternative to GM). So a couple of weeks ago, happy with the program and keen to step it up a notch, I decided to buy a personal licence, knowing full-well what C2 is and is not capable of (and, admittedly, also hoping for future native exporting when the time comes). The information regarding exporters is not hidden; it's freely available for anyone who takes a few minutes to read a couple of tuts or manual entries.
With that said, I agree that it should be clarified on the main page for those customers who jump in without taking a full look around, but, speaking just for myself, it's not a big deal how it is now. It's the Internet; I'm cautious of any piece of software out there, let alone one that I have to pay $120 for.
