The article doesn't give solutions because the alternative to an automated solution is a manual one. For most website owners that means every time they put up a new page, they have to pay their dev to make sure the page follows all the rules. And it's not just when they add content, just editing the layout of a page can kill compliance.

To compound the problem, as Ryan Bradford pointed out, the rash of ADA compliance law suits by bad actors is skyrocketing. Business owners have to protect themselves as best they can.

It's also fairly important to point out that users had issues with certain websites, not all websites that use this type of overlay technology. Garbage in, garbage out. Most websites using these services don't have the issues mentioned here. The sites that do have issues should be reported to the site owner or to the service provider so they can fix the issues.

These services are not going away unless someone figures out a batter way to automate the process. Better to help fix the issues they have and make the UX better on those sites than to try to kill the services themselves.
