To undermine my elitist credentials from the last hot take: ketchup is good actually as a master sauce. It's a complete blend of sweet, sour and umami thanks to the tomato, makes a great basis for other flavors, is surprisingly easy to make and adapt for different purposes with other ingredients but still perfectly serviceable in nearly all mass-market forms.
Ketchup deserves more respect.
Its odd, because I'm fond of tomato, but I've never liked ketchup on anything. I suspect its the sweet element.
