What do you call an organization that shoots itself in the foot with a thermonuclear device?
How did they do this?
By discontinuing the Abode Acrobat Reader for Linux.
Yes, Linux is a small part of the total market. Maybe only as much as 0.5. But it is the growing part. Apple is essentially static; MegaHard is shrinking.
No one debates the value of the PDF. But Adobe has now surrendered control of the PDF to the FOSS community, specifically the folks who write the Linux clients that read and write PDF. By removing their support to Linux of their vision of the file format they force Linux users to use other clients that create and read and manipulate the files.
And if the few, the increasingly few, who use other OS don’t comply with what the FOSS community does, the universality of the PDF is gone. And the people who use PDF can’t afford that.
Sic Transit Gloria Mundi.
