This font is an attempt to fix worst issues in the world's most reviled typeface while staying true to the general idea.
You're still not supposed to actually use the font yourself, but thanks to fontconfig substitutions having this package installed will help you survive weaponized uses such as the LibreSSL announcement or a html email from aunt June.
No lie - this is one of my favorite fonts and I make sure to install it on every system I use. It's a very readable and welcoming font that can make text feel approachable and friendly. Give it an install. Great font!
