Yesterday I joined the Free Software Foundation Associate membership, so I donate $10 per month now.
I think $10/month is a small money compared to the value and freedom I got from many free software I’ve always used.
If you purchase many silly apps on App Store and Google Play and never donate any money to the free software you use everyday, you should feel shame on you.
Free software is a cornerstone of any modern free society. Please help build this foundation.
