I think we're drifting away from the original point, which is about not letting corporate marketing departments decide how the written language should work. I used Swedish as an example of a language where this is a more firm rule than English, but Swedish is certainly not alone. It just happens to be the language I know best.

But, I do find the topic of Swedish writing standard to be interesting, so I'll be happy to do my best in responding to your questions, even though I'm not formally a linguist (although I was raised among them)

With regards to your question, I'd write Ios, because it's not an acronym and I do believe that I'm not alone in this. About the version number, I find at least one case of the use of Ios 10 at Svenska Dagbladet: https://www.svd.se/apple-har-atgardat-problem-med-ios-10/om/...

However, it seems to be highly inconsistent, and this is probably caused by these organisations saving money on proof readers.

Why do you keep repeating this? You say you were raised among linguists, but you're getting the most basic tenant of linguistics wrong. There is no such thing as "correct" language.

But more to the point, language allows you to write proper names as though they are registered or defined. It is not incorrect to spell it DigitalOcean, because that's the registered name.

If my name was JoeBob, you don't get to split up my name just because you think English requires it.
