Why did Samsung do that?

Samsung announced that the Galaxy Watch 4 would include a non-invasive continuous glucose monitor, which would allow you to monitor your blood sugar at any time while you wear it, for as long as you own it.

A months before the 4 was released, that feature quietly disappeared from all of the marketing, without explanation, and now, years later, is nowhere to be found.

I believe Abbott Laboratories, makers of the FreeStyle Light glucometer and the FreeStyle Libre continuous glucose monitor systems, panicked, fearing that a non-expiring, non-invasive glucose monitor would be hugely popular among diabetics, and devastate their death-grip on the market, paid a huge bribe to Samsung to drop the whole thing.
