Your correct, 1TB always meant 1 x 2^20

And before you start in again...
No that is not context sensitive.  The B denotes bytes, which denotes a
computer context, and therefore the metric context is no longer
applicable.  At least historically.

However, now that the SI has become standard, we can now allow TB to
take on the metric 1 x 10^12 and use TiB to mean 1 x 2^20.  Now we
eliminate context, and can say what we mean... Unless you are trying to
deceive?  I hope that is not what you are proposing.

Ubuntu is not the only distro having these conversations lately.  It is
time to start using the standard.  Standards are created to get everyone
on the same page.  I find it unsettling that the one guy arguing against
the standard set aside by IEC, IEEE, NIST, CENELEC, and the EU, has an address.  I would expect someone of that high level to
embrace not reject the standards of the industry.
