I wouldn't be so harsh, but yes, one gets the impression that
the author wants to reach that conclusion.

I'd agree with them on not chosing that option by default, though.

Definitely. If you care about minimising data leak opportunities,
keeping /tmp in an encrypted partition seems mandatory.

This would be a nice thing, yes (but we know that /tmp is, by default,
on the root partition).

One case where tmpfs for /tmp makes a ton of sense is when you want
to have most things read only (or read mostly), because your devices
die from too much writes (the Raspi/SD pattern, for example -- note
that I wrote SD, not SSD: no monster thread on that, please ;-)
