Rockit, though I understand your frustration (I own a CS406, which didn't even get v844), you bought the device knowing which features it had. Everything that was developed afterwards is extra and shouldn't be taken for granted IMO.
When you bought the device, you knew it didn't have support for Time Machine. It was fine back then to buy it, so not getting support for it now really doesn't change anything.
I do agree that Synology (and their resellers) should make it more clear that a product is EOL, the 106j is still being sold here as well. It's being advertised as having the ability to upgrade the firmware, which is clearly no longer the case. The CS-407e is even featured on the Synology website, though it will be EOL later this year if you follow the current trend. Having less than one year of software support is really, really poor.
So yes, I understand your point of view, but I don't think it makes Synology a bad company. And in the end, that's exactly what they are, a company wanting to make money. I bought my NAS second handed and after bricking it while playing with the firmware (my own fault), Synology made a new one for me that wasn't even supposed to be released for the CS406. I don't think support gets any better than that.
If you really want to upgrade the firmware, maybe Goetz's hard work
will provide a solution. It's not supported by Synology and will void your software warranty, but at least they allow it. They even allow us posting it on their own forums, including methods to create your own firmware. By comparison, Apple (of which you own a product) wilfully disabled support for the Palm Pre in Itunes a few days ago. That says a lot about Synology and even more about Apple (I'm not trying to bash Apple here, they have their own reasons for doing what they do).
