The origin of the company is irrelevant (even if the officer asked questions about this topic – they like doing that). Even if it had been a British company she would not had been allowed in. The rules are clear (Getting paid? Not getting in visa-free with very few exceptions).

And even if there would have been no appropriate visa to apply for that means the UK does not want those people in. Turning up at the border and requesting entry based on a reason not allowed on the visa-free program is not a solution no matter how wrong the situation feels.
