There are types of software for which I’d largely agree with you. Websites are not one of them: it takes effort or incompetence to make them slow and inaccessible.
You seem to agree with me, but refuse to admit it because you wish the world was different. I do too, but it’s pretty irrelevant.
Everything looks easier from the outside. Maybe we should focus on getting private corps to provide a small amount of accessibility before forcing onerous requirements on our already-underpaid civil servants?
