What about their mobile push notifications? I don’t understand whether that’s something one can self-host. I have just read Zulip’s https://zulip.readthedocs.io/en/latest/production/mobile-pus... and they give me the impression only they can do this, so ‘pay us money or else’

I wonder whether this is something any other provider can rug pull in the figure and to be worried about.
