Why is it so strange that someone ignored a convention?

Because it's a 50-year old convention, and there doesn't seem to be a compelling reason for ignoring it. The language then uses `is` for equality, including numbers. It's just weird, especially given they're using old-fashioned car/cdr instead of head/tail.

  This is not a Lisp, and never claimed to be one. This kind of gatekeeping from ANSI Common Lisp purists is tiring. Who cares about convention when one just wants to build their own language, use S-exprs and car/cdr for the sake of it.

    It's not like common lisps practices are that great anyways. It being an old lisp convention, to me, is actually a reason to not follow it. I want to see a modern take on sexpr based languages instead of being stuck in the past forever.

    It's not just 50 years old, it's widely conformed to for these 50 years. Why won't you use "&" for "less" and "%" for "greater", instead of sticking to the tired "<" and ">"?

      Slavery was widely confirmed for even longer. Tradition, right? How about instead of using tradition to decide if something is beneficial or not, you just assess it on its value?

This is an egregious use of the noncentral fallacy.[1] Conforming to this 50-year tradition makes the language more familiar and easier to learn, so it's reasonable to question why the language chose differently.

        And yet, Clojure, the most used Lisp today, decided to use brackets instead of parentheses for parameter lists, breaking with 50 years of Lisp tradition. How dare they?? But I'm sure you know better than them.

        When Lisp first appeared, square brackets were not even standard characters. Maybe McCarthy would use them if he could. The word "set" is much older, and is universally supported. But most glaringly, (= a b) has a well-understood and entirely different meaning in most lisps, also since 1950s. It's comparison, not assignment. Breaking a well-set convention is a very different thing than making a new, slightly improved convention.
