TL;DR Telkom does HTML injection on all unencrypted traffic of its customers, whereas the author of the linked blog uses #444444 text color on #000000 background (which gives contrast ratio 2.2 on http://leaverou.github.io/contrast-ratio/). I call it almost a draw ;)
Sorry I had to be that guy. Please improve contrast on your blog.
