That's entirely the fault of the commercial organisation for choosing a trading name which is so readily mis-spelt. It is based on a common name but with a less-common spelling.
Likewise Easyjet. Proper nouns are spelt with an initial capital letter. If some marketing type likes it done differently, so be it, but the rest of the world does not have to follow the mistake.
