horrible, horrible font on the website!
Just override the font if you dislike it that much. That's the great thing about the interwebs, it's all just text, you can format it however you want.
Assuming you're using something based off chrome: https://chromewebstore.google.com/detail/font-changer/obgkji...
Or Firefox: https://addons.mozilla.org/en-US/firefox/addon/refont/
What I'm getting at is that they might (unintentionally) be complaining about a rendering bug and not the actual font...
"Just use an extension that changes the website bro!"
As another commenter points out, you may have some rendering issue. Alternatively, you may just not like the font. Can't please everyone.
