Change for change’s sake. I feel like F/OSS has a potential advantage here in being able to take the time to build durable, long-lived, stable software.

The web-everything world we live in right now has led to a cambrian explosion in new UI metaphors and visual design. I can only hope at some point we all wake up and decide that GNUMail running on GNU Hurd has gotten really stable, and that maybe we should all just re-adopt open protocols and native apps.
