Well, I don't know how they actually see it, but I get why at least on this side of the planet people would think of it as nothing more than masturbation fodder  I mean, I know I do.
And the reason is that sex scenes are usually so over the top that they often feel like a parody. I know I'd love myself some more intimate and romantic h-scenes, but heh, good luck with that. It's like in anime related media everything has to be exaggerated, including sex. Well, when you think about it and compare it fairly with every other aspect, like comedy, it actually makes a whole lot of sense.

What Maggie said. They usually go by aliases, so it's not like they absolutely don't care about being recognized as eroge voice actresses.
However I think it's true that there's a big conceptual difference in the way Japanese people see their porn in VNs. Because yeah, most of the times, h-scenes are just porn, the cases when it actually adds something to the story in any form being pretty rare. Let's call it what it is, and it is porn. 
The thing is, in the west in general (and EEUU in particular, I dunno, I'm not 'murican) we kind of have a really hard time wrapping our heads around how porn could be anything more than porn. Either it's a porn movie, or a 'normal' movie. No in-betweens. That doesn't seem to be the case in Japan. You can have an amazingly written story with some porn on top of it to spice things up a little, and nobody bats an eye. And honestly, being so used to it nowadays, neither do I anymore.

Actually it's not that much different in Japan tbh
See, the thing with your quote is that it's Tara Strong. She's well know, of course she wouldn't do any random pornographic scene. Now back to Japan. Did you tried to look for eroge voice actresses? A lot of them go by alias and good luck if you happen to find a single pic of their faces (Of course there are exceptions, like Aoba Ringo). They mostly do eroge and eroge only. And actresses like Sakamoto Maaya and Kawasumi Ayako don't do eroge, except in all ages versions console ports. They're also more well know and they show their faces in events and such.
