I think the term "web push" defines a process in which data is pushed to
a client regardless of the clients current connection status. In other
words - as long as the client maintains a connection to it's server,
it's not really web-push - at least not in the sense the term is used
today. This having said: Apple, Google and Mozilla maintain their very
own web-push environments. It is convenient to use FCM (Firebase) as it
provides an API that enables us to send messages to all operating
systems - but it also gives a single entity control over all
environments. In our work, we try to push to the individual endpoints -
if we have data for Apple devices, we push to Apple, the Mozilla data
goes directly to Mozilla's servers and everything Google is delivered
via FCM.

Unfortunately - web-push is also highly useless for anything that would
really benefit from urgent notifications - such as important messages,
incoming Web-RTC calls or the like because a) Google / Chromium devs
seem not to be interested in fixing a bug that prevents web-push from
cutting through doze on Android-devices and b) Apple doesn't have it
(yet) on iOS. And even if the push reaches a device, all one can
currently do is to display a notification. It won't be delivered to your
app or web-site so you can't fetch data in the background and display it
whenever the user is ready.

It's sad - because web-push really could be a cool way to distribute
content and information, but it is not - at least not as it is today. As
to the question of whether or not there are overall volume stats
available ? You will need to get those from all providers and add FCM
distribution channels to get a good picture.
