I think you're talking about the HUD agreement, which was not the direct result of any "big" court case, and is dead.
Current changes in S&W are more the result of being bought by the Safe-T-Hammer Corporation (integral lock) and to reduce manufacturing expenses (MIM parts, two-piece barrels, changes in rifling and other dimensions, etc.).
Many people think the older guns are better built, many people think the new ones look just fine.
The outsides do look pretty nice on the new guns, but in specific areas that more knowlegeable shooters look at, the old ones are better overall, in my opinion.
You'll get other opinions.
We won't know how well the new guns hold up till they run for another 20-30 years & we have a genuine longterm basis for comparison.
