There are more options, but they all involve giving up something somewhere. Perhaps you have a secure, easy-to-use, useful site, but charge more money for it. Perhaps it means that people can't use it
today but can in a year. Perhaps it means that you've hired gullible underpaid engineers on promises of future wealth and then work them to the bone, but then do you want to be the person who's underpaying your employees?
The point (of both my comment and the original article) is that there are trade-offs, and you get to choose which trade-off you're going to accept, but anything you do is likely to piss off someone, so choose who you piss off wisely. Do you want your top priority to be accessibility? It can be, and that could be a wise choice if you identify a task that really really sucks for disabled people. But if you're looking at that before you've even got the fundamentals of building a useful product down, you risk building something that does something nobody really wants to do but does it really well.
