Before mibi-, gibi-, tibibytes, etc. were a thing, it was the harddrive manufacturers who were creating a little. Everyone saw a kilobyte as 1024 bytes but the storage manufacturers used the SI definition of kilo=1000 to their advantage.
By now, however, kibibytes being 1024 bytes and kilobytes being 1000 bytes is pretty much standard, that most agree on. One notable exception is of course Windows…
The IEC changing the definition of 1KB from 1024 bytes to 1000 bytes was a terrible idea that’s given us this whole mess. Sure, it’s nice and consistent with scientific prefix now… except it’s far from consistent in actual usage. So many things still consider it binary prefix following the JEDEC standard. Like KiB that’s always 1024 bytes, I really think they should’ve introduced another new unambiguous unit eg. KoB that’s always 1000 bytes and deprecated the poorly defined KB altogether
M stands for Mega, a SI prefix that existed longer than the computer data that is being labeled. MB being 1000000 bytes was always the correct definition, it’s just that someone decided that they could somehow change it.
Consistency with proper scientific prefix is nice to have, but consistency within the computing industry itself is really important, and now we have neither. In this industry, binary calculations were centric, and powers of 2 were much more useful. They really should’ve picked a different prefix to begin with, yes. However, for the IEC correcting it retroactively, this has failed. It’s a mess that’s far from actually standardised now
I think there were some court cases in the US the HDD manufacturers won that allows them to keep using those stupid crap units to continue to mislead people. Been a minor annoyance for decades but since all the competition do it & no govt is willing to do anything everyone is stuck accepting it as is. I should start writing down the capacity in multiple units in review whenever buy storage devices going forward.
So what you’re saying is that … we can make up whatever number and standard we want? … In that case, would you like to buy my 2 Tyranosaurusbytes Hard Drive?
The 1024-based magnitudes, which the computing industry introduced, were non-standard. These days, the prefixes are officially called kibi-, mebi, gibi- etc.: https://en.wikipedia.org/wiki/Binary_prefix
They could easily use the proper units, but sometime someone decided to cheat and now everyone does to the point that this is the standard now.

Indeed, Windows could easily stop mislabeling TiB as TB, but it seems it’s too hard for them.

B and b have never been SI units. Closest is Bq. So if people had not been insisting that it’s confusing noone would’ve been confused.
does not mean you can misuse SI prefixes if the unit itself is not part of the system.
Not sure why you’re getting downvoted for spreading the truth. It’s Windows’ fault.

And as far as my wife is concerned, I’m definitely 6 ft tall. Height ain’t what it used to be.

Nah, the prefixes kilo-, mega-, giga- etc. are defined precisely how hard drive manufacturers use them, in the SI standard: https://en.wikipedia.org/wiki/International_System_of_Units#Prefixes
