The ADA may not require it, but the compliance costs it imposes are a strong disincentive for publishing. The ADA in that case turned an unmitigated public good from "Sure, why not publish them online?" into "We can't publish this content without paying a lot of money we don't have, so we just won't publish it.". In this case, the ADA has left society worse off.
