> Have 5k users on Android, 3k on iPhone, 8k on web. Add them up to show the product has 16k users.

If it's a traditional desktop program like Word or Excel, I think it's perfectly fine to add up users from different platforms (which often even require a separate purchase). If it's something like Skype or Netflix, I can see how there might be some overlap -- the same person might use it from their iPhone one day and from the web on a different day. Is that what you mean?
