It's an odd 4 letters to choose, isn't it? I get 'G', we already have 'J' they're basically interchangeable. Maybe I can be convinced that 'V' is a suitable replacement for B. But L & T?!?
And how did C&K avoid scrutiny? I mean sometimes C makes the K sound, sometimes the S sound. I'm no fan of K either, I mean sometimes it makes no sound at all, it's basically a freeloading deadbeat letter. In my view there are only two possible explanations. Trump is in Kellogg's pocket and they don't want to rebrand Special-K or Trump is a closet Klans-man.
