If you have the time to post on HN, you clearly have the time to change your email provider if it aligns with your personal beliefs.
Why do you feel the need to bring up personal details about your hardships in life? Being no longer homeless, you are, globally speaking, on the upper scale of social classes yourself, being from the United States, having 6 years of university, having worked at a Fortune 200 company, and currently having enough time to post on HN.
I speak from firsthand experience. Many people do that on a regular basis here, but their firsthand experience is as a comfortably well off male so no one has any objections to them mentioning their gender, the kind of work they do, their general social class, etc.
Suggesting I should not ever mention any of the details of my life amounts to trying to make sure no comfortably well off people need to be disturbed by the awareness that people like me exist and it de facto takes the position that my life experiences and points of view are less valid than that of people with cushier lives and fundamentally not welcome here.
And I don't only talk about my hardships, of course that fact also gets used against me. Never mind that my life is still far from comfortable, if I have time to post to HN, my life is too cushy to complain about. Wow. The denial here runs deep.
Meh, changing email addresses is a major pain in the ass. So much so that I've hosted my own mail server for decades, including configuring sendmail, to avoid it.
Changing bank addresses (aka accounts) is comparatively easier and there is real money directly on the line, and yet banks still clearly make loads off of account stickiness.
Posting on HN is procrastination.
When I was homeless, one of the places I could get a free shower had an open bay of 8 showerheads where I could shower with up to 7 strangers. I could get showered or I could protect my privacy and dignity. I could not do both. I needed a shower more than I needed to make sure total strangers never saw me naked.
Maybe you have heard the expression Beggars can't be choosers?
I did everything in my power to make judicious choices under extremely difficult circumstances. But the most charitable read I can give of your question is that you are so privileged, you honestly don't get it. There are people who are doing everything in their power to fight the good fight in spite of poverty and myriad other burdens. And at some point, you have to make compromises. Maybe you get the free option. Or maybe you become a criminal because it pays better than the legal gigs you can find. Or you make some other compromise because there simply aren't the above board good options available to you that you wish there were. Period.
