If only. The problem is that businesses on the web directly benefit from things being not accessible.
Attention economy makes money on friction. Your typical website is a maze the user is supposed to get a little lost in, to maximize time they're exposed to product offering, and/or third-party ads, and/or tracking. Cutting curbs just tells them where to go and lets them do it with less effort, so they cut through the maze faster, and business loses money.
That's pretty selective view of the problem. And I'm also pretty sure it's at least partially a fallacy that even some these businesses are fooled by. Removing friction often increases your revenue, that's been shown in many cases, often by the companies you seem to be criticizing here.
