Yes, WT used to be far more open. Their decision to only post AODA compliant documents on the WT website is VERY annoying as it is now necessary to specifically ask them to send you documents like the Board Books and Committee and Design Panel Books. All the older docs (like all the earlier Reports and meeting info) are now hidden and hard to ask for if you do not know they exist.
I realise it is simply too hard to make all older docs AODA compliant but other governmental bodies continue to make all documents before some date available (even if not AODA compliant) and then make all docs after that date compliant. AODA is a good thing but it is really not designed to make information LESS available!
