Because most companies don’t.
You can see that just from looking at their websites. When you know, it’s obvious, really, but it just means that there are all the more opportunities when you start to make it work for you.
If you want to sell something to people, you need to attract their attention, gain their interest and be so compelling that they take the action you want them to.
Even though they don’t have the passion for your solution that you do. Even though there are many other things competing for their attention – like the latest cute cat video on the internet (businesspeople are still people, after all).
And to do all that, you need to talk to them persuasively and inspiringly in their language. Which is impossible if you don’t speak that language well. (And I mean really well; for everyone thinks they can speak English…) Or if you aren’t a professional writer.
So that’s the secret. Simple as that.
