Agreed. Obsolescence is one thing. But, your remote will still change channels on your TV until the TV dies and even if they quit broadcasting, you can still use your VHS (LOL - Yes, I still have 30 year old tapes) unless you buy a new TV without the inputs. There, it is a choice of whether or not to upgrade. For your car, your stereo will continue to play FM stations until they quit broadcasting or your stereo dies. To remove BASIC functionality is more akin to making your car or TV unusable from a software /firmware update requiring you to replace the system or key components that were basic to it’s functionality. If you had to go buy new seats, tires, headlights, and more because they did a firmware update and then said your old items were obsolete anyway, that would not sit any better than this.
That said, we knew this was a risk when we bought into the cloud architecture with forced updates. Samsung absolutely has the right to change anything they want at anytime they want. Having a legal right and doing what’s right are two different things though.
I recall that we were promised that before we moved, equivalent functionality would be provided. That hasn’t happened. And in some cases, looks like it will not happen.
As you said, many of us will exercise our right to voice our dissatisfaction publicly and take our future business elsewhere. I’m keeping a few non-critical items on ST long enough to see if anything usable (to me) is left when the dust settles. Otherwise, I have no loyalties to a company that does not return the consideration.
