Have you considered that it’s not indecipherable or clownish and perhaps you are a part of a group that just doesn’t get it?

Not OP, but that’s my conclusion. I also don’t like programming font ligatures, but I personally find it annoying when people who share my opinion feel the need to point it out in a discussion of fonts clearly designed for people who don’t share my opinion. It’s highly subjective and the prevalence of these ligatures has never been a huge burden for me, because fonts without them are rather prevalent as well, as are means to bypass them in my own use.

And you can use the font with ligatures disabled! Almost as if having ligatures was a preference that doesn’t influence those who don’t want them yet may convince someone who does to try out font X :)
