It’s never been cheaper. It’s so much easier to scale. It’s never been cheaper. Well, maybe at a very low usage rate. But, at scale, it’s never been cheaper.
Buying server hardware is a lot more difficult and with more lead time than just buying a computer. Plus you then have to build your server infrastructure out in a data center. It takes a lot of time, and specific logistical skills. AWS is far easier to scale your services then doing it yourself, especially if you have extremely high peaks that you have to serve.
If AWS was cheaper then hosting, they wouldn’t make money.

You effectively have no user id’s with chatmail relays with DeltaChat. Routing of messages uses the default TCP/IP stack and so you can just use TOR if you want to. Mentioning a chat systems ability to use TOR, as if that should be a part of the chat program rather than the system it self seems strange to me.

Federated servers, Multiple device access without the phone app being open, Decades old tried and true backend protocol that would be a problem to ban.

Nothing you wrote was a response to what I wrote.
I also don’t care what you ‘studied’. I lived it. Google and Apple were literally, and this is a quantifiable fact and not an opinion as you seem to be treating it in your response, the 10 person startups that were going against industry behemoths.
Yahoo was, at the time, was a Juggernaut.
I.B.M., at the time, was a Juggernaut.
Or, you can skip the unhinged rant, use monocles or dino, and a public server.
Also, hosting a server is much simpler than something like matrix. You can host an xmpp server on a pi and that is more than enough. Or, just use a public server.
So difficult.
I like how you included steps that absolutely aren’t required and haven’t been for like a decade to make your statement more hyperbolic.
You have it backwards.
There are some very few specific use case that most companies don’t ever meet that makes AWS cheaper. In the vast majority of use cases it is an order of magnitude more expensive.
