The Reviseberg team builds the product and writes the guides on this site: people who have designed and built accessible interfaces for agency clients since 2013, on the receiving end of a great many audit reports and on the building end of the fixes.
We write the guides on this site and answer for them. Pages that state the law are additionally reviewed by a lawyer, named on the page. Reviseberg is not a law firm, and none of its pages is legal advice.
