I strongly disagree, also the way the article describes subpixel antialiasing is not entirely accurate. The thing is the boundaries between pixels don't actually exist, it's just a convention so we can address individual pixels and subpixels within them. But these subpixels are not at the same position within the pixels and this needs to be taken into account for antialiasing.
Also regarding hiDPI: I know that you just want to get rid of subpixel antialiasing but you really don't want to get rid of antialiasing in general. It's not really an issue with typefaces, but non-antialiased high-frequency patterns can easily generate unwanted Moiré patterns on you display regardless how high is your display resolution.
