There are laws preventing you from ignoring wheelchair accessibility. As a society we have decided it is important. We’ve done no such thing for keeping information on Facebook only.
We have those laws because we had already decided that was a Not Ok business decision. That was true before the laws came into effect, and would hold even if we didn't manage to pass the laws at all. Moreover passing laws is not the only way to express a shared moral judgment. Anyway, I was very explicit about it not being exactly the same situation.
