It isn't taste. That font is barely readable. Worse, their encoding wasn't UTF-8, so a lot of their punctuation showed up as black rectangles, darker and solider than the text. I had to fight to keep my eyes from skipping from black block to black block without reading the spindly gray text in between.

It's not about taste, but about readability, a part of usability. Why act like a technologist while flushing about 50 years of usability knowledge (Helvetica is from late 50s) down the drain? Heterospaced fonts with significant contrast are used widely for good reasons. Ignoring these harms credibility of the writer severely, at least for me personally.
