This rule does not conflict with the central freedoms; rather it protects them.
Foxit Reader is free for not just reading, but also creating PDFs and collaboration on the files (at least you can with the Windows version; Mac and Linux are more limited). Foxit's MobilePDF apps are on iOS, Android, and Windows Phone. What's more, they support a tech called ConnectedPDF so you can send PDF files and even update them after you send them (thanks be to the cloud).
To the best of our knowledge ALL listed programs were completely free for non-commercial use when first listed and we encourage users and program authors to report any instances where this might not now be the case. Users are reminded that some software authors change their program’s status from freeware to shareware after it becomes popular, as is their right.
