Continuing on your line of thought, and being a bit pedantic, the title says missing from the internet, but it looks more like missing from websites.

There is a lot of internet interaction that happens privately/semi-privately in chat applications like Whatsapp, Facebook Messenger, LINE, etc.

From my limited personal experience, communities who speak and are able to write in minority languages continue to do so in their communication via these apps even though they may have a small appearance on public websites. Of course, for communities that do no have a written form for their language or very few know it, then this is less likely the case.
