Then why are you in a dark wood, knocking on the door of a witch's hovel, begging for candy?
Because that's what the corporate internet is, a tumble-down trash-heap, a sewer, filled with hucksters and peddlers. Any place that presents as an informational site but asks for your email address, just laugh and move on. There's no need for it. There's never been any need for it. It's a clear signal of ill intent. So why stay for the abuse?
The real internet is still there. Maybe you just stopped seeing it. It's on millions of small personal websites, on the internet archive, wikis, forums, via torrents, IPFS, Tor sites - but you won't find that through Google or other broken "search engines" - they just lead you back to the witch's cottage.
There is a world of immense value, kindness and reciprocity out there. But it's 2022, so you have to work extra, extra hard to find it.
Think if the tech sites allowed for student access like a Facebook social loving integration. Instead of directing to fb they could be directed to an IdP which contains validated age metadata that the sp would accept and then minimize privilege gates?
Besides - most of this give-me-your-email is just to get you into a marketing channel and drip emails on you anyhow. In my experience very little info is behind this crap that cant be found elsewhere.

Anyway, does the set of people that never eventually learns how to anonymous email addresses meaningfully intersect with the set of people that will ever learn any meaningful amount of knowledge about any technical field?
