It was a balance fix, balance will happen to the game and the vast majority of players will support continued balancing. Expect to see a lot more changes to both runes and sockets, especially on neckalces, since they trivialise crits.
As I said before, If you want to cheat to add sockets, do so. You don't even need a mod to do it.
If the problem is that you don't know how to: use cheat engine, or edit your game's files, there are plenty of ways, some easy, some not so much. Cheat engine is probably the easiest way unless a mod exists on the workshop to do what you want specifically.
