Yes, the color space is always sRGB, but there is no calibrated profile data included with the images which would try to manipulate the color. No monitor profiles, no game correction data, etc. No color management information. It's up to the target to manage their own color to render the sRGB for their own output devices.

The biggest issue caused by not doing this is with images used to build pages, not so much presenting a portfolio of photographs as the author of that article is focusing on. Nevertheless, his original image was bad and it shouldn't have been up to the color profile to fix it. But of course he did that on purpose for illustrative purposes.
