Rhetorical question- but what is it going to take for the IT Community to start treating Gmail and the rest of the "too big to block" as adversarial entities and actually block them for their bad behavior. Pie in the sky I know.
No such thing. And if you just want to assign anybody who works in IT to it in order to create the concept of such of a thing, a large percentage of this community would work at Google, a company that depends on Google, or a company that has the same attitude as google.
So it's less pie in the sky than nonsense. People don't talk about things changing in the physical world without talking about force, mass and inertia, but when it comes to people, the theory of power just evaporates and we start wishing for things to spontaneously happen because we've declared that they should happen.
With some weird definition of "should" which relies on our personal conception of the world. In the physical world, we say something "should" happen when we expect it to happen based on our theories of how the world works. With people we say things "should" happen when we personally want them hard enough.
Before Google, AOL were the previous big-beast mail host, and they did provide some tools to help diagnose why you couldn't get through to their users. It still felt like there was more of a balance of power towards the grumpy sysadmins.
I’m not jumping through hoops when I’m not doing anything wrong. SPF, DMARC, DKIM, IP address not on a blacklist, and I send zero spam. Only human-written client communications 1:1.
So, my clients with hotmail.com addresses don’t get emails from me. I can call them, they can call me.
