I've observed this over the last little while trying to use the Optik TV website to watch shows on my Linux machines in Chrome. The reason why I think this seems intentional is there is no dependency reason for it to not work. This idea is proven when you use a User-Agent switcher to switch the platform reported by your browser to Windows instead of Linux then everything works as normal.
So why is Telus almost seemlying intending to block the ability to watch Optik TV on Linux?
Well that's what I meant before by it wasn't a dependency issue with Google Chrome instead of Chromium on Linux a built-in flash player version is supplied one that is more updated and secure. The User-Agent trick doesn't effect the OS reported by flash player and that's clear by the way Shaw blocks Linux platform users from their Free Range TV platform. The User-Agent will get you in the door but if you try and play anything you get hit with yet another error from Flash detecting the platform.
It's very clearly not a flash player issue.
