Earlier quoted context omitted.
I think it's kind of weird to see Google/Firebase team members swarming around in dozens on HN when they present a new feature, which seems to me like a coordinated marketing effort by Google. But once problems arise or they get criticized by their own users, no one seems to be available for a comment.
Or it's just engineers that swarm around since that's the demographic here but this needs a response from PR, not from engineering. What do you want google/firebase engineers to say? The engineering response is pretty clear-cut. Polling every minute from an uncached SSL connection is expensive, don't do that. That's pretty obvious and the author admits this was a mistake. The complaint is about everything that's not…
I'm sorry, I can have 50'000 devices poll every minute via an uncached SSL connection on my 16$/month server from Online.net, including bandwidth and traffic costs.
I'm not sure what you're smoking, but I want that, too.
Seriously, at Google, TLS is terminated in hardware, and bandwidth costs less than a cent per terabyte for ISPs or Google.
The costs that this caused are basically nil.
(This, btw, is why I'm using kubernetes on rented bare metal, paying 30$ a month, for what would cost me, including traffic, around 900$ (Google Cloud with rented servers) to 63'000$ (Firebase) a month.)
