Not only for dyslectics. People with disorders such as Myalgic Encephalomyelitis and other conditions with severely limited energy reserves pay a huge cost reading hard to read fonts, causing them a decrease in uptime in general.
Note though: I've gotten FFZ to work to replace the new font. But having to rely on plugins to use twitch at a base level locks out use on other than your own machines.
