You've basically arbitrarily focused on a particular flawed design decision of a language while ignoring a thousand others that they may well have gotten right.
It's not possible to just sit down and get everything 100% right up front. The language design space has too much both depth and breadth to it.
IMHO, you may be confusing “care” for legibility. The creator(s) made a choice that you disagree with and that you may not understand. They also haven’t justified or explained their choice to you. That illegibility might feel careless, even a little mean, but I reckon their focus was on figuring out the language, not seeking widespread approval.
