In modern times and days of cheap storage in cdn server farms and good codecs, it would be great if you wouldn’t shut down access to videos (which i can no longer store myself due to DRM) a few weeks after blizzcon ends.
We paid money, you probably store the event videos for yourself, why not alklow every virtual and real attentee to watch past events for ever as long as they paid for it?
I would even pay a little bit more on the virtual ticket if it allowed me to watch all my old blizzcons later on without fear of not getting it done or forget about it just because its summer after blizzcon.
It is your trademark, your event, your intellectual property.
So it is up to blizzard alone if stuff can remain accessible.
Please do consider it this year. Maybe switch to VP9 ,HEVC or AV1 to reduce storage costs, but don’t lock us out.
