All I'm saying is, if enough people post on Lemmy or elsewhere "Install this software! It's exempt from paying to access the Reddit API so it still works!", at some point Reddit will take notice, throw a fit and shut it down. And the losers will be blind people.

Whether you reckon this application should be accessible to everybody or not, and who you think qualifies as disabled is totally irrelevant. What's important here is, Reddit, in its very limited wisdom, has "generously" allowed a good app to exist for free because it allows the blind to access their site. Don't make them think it's being abused by people who aren't blind, is all.
