Or just watch it on PC or mobile phone or any other device that is supported by google.
Getting into complex stuff like this just turns the average Joe E. User away. As the functionality wears away, they will replace it with a device that does what they want. Chromecast, for one, or a HTPC if they want something more.
At the end of the day, for WD to let their products lapse just means people will be less likely to buy their products in the future (seeing there is no ongoing support) and people will look elsewhere. The problem here is twofold: The support has disappeared, and there is no replacement produt already on the shelves for some time.
Apple would certainly have a Live Hub 2 Air Mini Pro (or some ridiculous moniker) - but the point is there would already have been a new, improved version that people will already be looking for an excuse to buy to replace the product before support was terminated. Microsoft don’t pull support from previous versions of windows until they have several evolutions of the OS already distributed. The failure here is not continuing to offer the customer a legitimately wonderful product in a continuous fashion without any gaps.
I worked in retail selling these very items for years; consumers left with a disappointing product rarely buy the same brand again - they cite “Nah, that last one of theirs I bought was rubbish, I’ll get Brand Y this time”. Once you lose a customer, they are hard to get back.
As it stands, being a WD fan meant I sold loads and loads of WD products over their counterparts from other brands, but even now I am starting to lose my faith in them. Hard to recommend something that you won’t buy yourself.
The alternatives here are games consoles or Intels NUC. Both always have ongoing support and are upgradeable in terms of the software - and a replacement arrives before the old one becomes obsolete.
For the lighter user, there is Chromecast or Apple TV.
For WD to maintain any semblance of trying, there would have to be a set of unified prducts under the “WD Play” name brand, with different levels of functionality easily distinguished. The support would have to be ongoing, firmware/software should be upgradeable, and if they had an SDK they’d draw in a massive modding community once word got out you could fiddle with the thing.
But what would I know? I only saw what average end users wanted every day.
