You don't seem to agree with the post as a whole, so I'm curious: 1) Did you expect the post to include reviews of applications, so you could learn from that, or 2) Do you think the design quality of FOSS is high enough?

If it's the latter, I'd love to know your examples of apps that meet the criteria I listed: - Is free to use - Has open source code - Has a user base that doesn’t primarily consist of software developers - Has a GUI - Is mainly created and maintained by volunteers

Is there one you would recommend over commercial alternatives _because of_ its design?
