Yep, this whole article misses the point that the gamma wasn't being corrected for, so the opacity wasn't linear relative to the requested percentage. Sadly, the only thing that ever did this correctly was Firefox, and it no longer does it. The proper method needs alpha values maintained for each subpixel in an image, not just each pixel, and it needs a specialized blit routine to composite with the background. This was agreed by most to be too complex, and, as other comments point out, DPI is increasing, so the easiest thing is to just disable subpixel rendering.
