In my (much poorer than Norway) country we have that, and also women can't be fired for that duration and I think two years more and employer can't refuse then remote work if it's technically possible and parents get some money directly (~around 1/10 of average monthly salary per month is automatic, but also there are other programs for example for women who decide to return to work). And, as a young parent, this is still nowhere near the cost of takes to actually raise a child.

On the other hand, all those programs are still not enough to raise number of children significantly, so your main point stands.

Unencrypted messaging is easier and more convenient, just login from anywhere and done. So there are actual technical and rational reasons to choose against e2e.
