MS is not trying to make their Surface product fail. The above article covers some good reasons for dropping live tiles. Personally, when I still had a WINDOWS phone, I found that the tiles were an "iffy" proposition in terms of their working especially after various updates both from an MS engineering issue as well as an app developer stance.
On my WIN-10 laptop, I don't make much use of live tiles except for mail notification. I find the Rainmeter options for system and other tracking do very well with a lot less overhead demand.
