It is again quite bad thought. I mean they have had years to do that audit. Actually without taking accessibility concerns SERIOUSLY into consideration they simply should not have begin coding the UI at all.

Now as there are only some days until GB lands in core they just want money for that audit?!
That is a complete non-sense as they will get that audit cost free from people living with accessibility problems the next day as GB ships with core.

And by the way any audits are completely useless if they just do not listen and change their mind.
