As some empirical evidence, look at how few StackOverflow sites there are in other languages: https://stackexchange.com/sites?view=list#technology-traffic. Just three (Russian, Spanish, Portuguese), all were introduced 5+ years after the main site started.

Similarly, Github doesn't have localised versions.

There are certainly clones in other languages (e.g. https://teratail.com/ clones SO in Japanese), but it shows how little demand there is when these well-funded platforms for developers de-prioritise local versions. I couldn't imagine a comparable platform for lawyers or accountants doing same thing.
