Literally in the next line he says that the conference rooms were always booked and not really an alternative (which is pretty standard in any office)

That's a different issue now isn't it? Access is provided but not guaranteed. You don't see cities with bike lanes forcing those lanes to be clear.

I don't think it is a different issue. The object of the exercise is to allow disabled people to participate on an equal footing. A few nominal concessions that aren't sufficient to achieve this does not do that.

I don't think blocked cycle lanes are a good point of comparison as they don't fulfil their intended function when blocked.

If the accessible alternative isn't really an alternative then I don't think that's a different issue at all.
