This is absolutely true. Perhaps Microsoft have painted themselves into a corner, their catch-all marketing racking up significant tech debt. But in the same breath I honestly can't see what the value proposition would be for their office applications without it.

Regarding your first paragraph, if you're curious, I work for a multinational where we deal with company names, this is kept uniformly in uppercase in our internal system, globally there's too many variations and it gets visually messy (such as GmbH, there's also user errors to consider). However emailing external third parties, it looks a little unprofessional sending this information ALL IN CAPS.
