All of that was well and good in 1990, when the then-nascent Internet was not the ubiquitous presence in the lives of Americans that it is today. For example, retail shopping in-person at a mall in 1990 was booming, unlike today where online shopping has completely changed the game for retailers. As time and technologies evolved however, the Department of Justice (DOJ), the entity charged with enforcing the ADA, hinted but never definitively stated that Title III may indeed be applicable to websites.
VERY useful. I searched for a plugin that had WAVE scanning integrated and this plugin came up. I was a bit hesitant because there were only a few reviews and the price was higher than most plugins. However, if the plugin worked, it would save me $1,000 from requesting a WAVE scan of my entire site. In short, this plugin is amazing. It is super-detailed. That makes it a bit longer to learn and master. However it makes it amazingly useful. If you take compliance seriously, this is the plugin for you. I am not a developer, but understand more about coding than the average content creator. I was able to understand this plugin, though it took several hours. Don't take that as a bad thing. It was necessary, and I learned a TON about ADA compliance in the meantime. When I had a question, the author was super-fast and helpful. I highly recommend this plugin.
