The link to the I2C specification is broken and is replaced in this

Although `https://www.nxp.com" hosts the Rev 7 (2021) of this
specification, it is behind a login-wall and thus cannot be used.

Thanks for pointing out this issue!

 The official I2C specification is the `"I2C-bus specification and user
-manual" (UM10204) <https://www.nxp.com/docs/en/user-guide/UM10204.pdf>`_
+manual" (UM10204) <https://www.pololu.com/file/0J435/UM10204.pdf>`_

I'd think we should have two links. One to the latest official specs,
even though it is behind a login wall. And one to the latest free
version. For that, I think the archieve.org address which Wikipedia uses
is more stable thant the pololu address from above:

What do you think?
