Some reader comments in that article seemed to suggest that VDR is becoming obsolete due to streaming services and RaaS cloud services (recording-as-a-service). Those readers seem to forget two important issues: privacy, and availability of service.
Add preference to that list as well. Streaming tv isn't making anything obsolete, it's simply another option to choose from. VDR has nothing to worry about, I have no doubt we'll continue to celebrate development milestones and anniversaries.
