May I ask why?
Case sensitivity is one of the things that really bothers me on Linux, it causes me to make mistakes for no reason. If I ever really switched to Linux full-time, I’d probably want to change that.

Case sensitivity wasn’t designed; the first Unix couldn’t spare the CPU cycles to do case insensitive matching, which was the norm at the time.
Don't you think that 65 ≠ 97 is sufficient of a reason?..
I mean, 'A' ≠ 'a', in ASCII, Unicode and even EBCDIC. In computers, those are two distinct characters. This fact won't change no matter how you rationalize your expectations.
Thus, pretending that "y.txt" is the same as "Y.txt" is an elaborate lie. Even acknowledging that it's a "white", well-intentioned lie (designed to preserve the mistaken expectation that "y.txt" is the same as "Y.txt") — I don't like when computers lie to me; do you?
As every lie, this one has weird consequences. One of them is the today's RCE in OP. Another one was CVE-2014-9390. Myriads others.
Linux rejects the whole notion of filename case-insensitivity, and demonstrates how computers actually work. It becomes easier on developers and more secure on users.
Lastly, don't feel that I'm attacking you; I'm opposing an idea. So, here's a tip: you can set up case-insensitive filename completion in bash, so that TAB will correct your casing mistakes for you. It's a simply one-line change involving putting `set completion-ignore-case on` into an inputrc.
In computers yes, but i am a human and to me as a human 'A' and 'a' are the same letter.
We do have the options to ignore the fact and say "What bytes? I don't care. Guess what I mean, and lie to me as well as you can so I can stay happy in my ignorance" — but, see, coordinating good support for that isn't easy. Minor wrinkles in it continue causing burns, sometimes RCEs. Maybe "doing in Rome as Romans do" isn't such a bad advice after all?
It's almost comical: people continue insisting on "letters not code points" knowing very well how computers are bad with guesswork and under-defined notions. Issues stemming from that keep coming up. What if, instead, the norm accepted that 'A' ≠ 'a' and stopped creating problems which computers are known to deal poorly with?
65 ≠ 'A'.
