So we tend to think less of misspelled words in brand names. I'm not surprised.

We think less of people who can't spell correctly, and don't recognise the difference between "its" and "it's", etc.

Or if they use a weird slang.

At least after the first 20-some years of our life most of us do. :)

I think it should have been obvious to the brands a long time ago. But then these things are created by people who work in marketing, and those aren't always the sharpest tools in the shed.
