The short version: that's when Xi Jinping took power and started very quickly undoing all kinds of moves toward moderation and reform that had been undertaken by the previous few leaders.
He ramped up control over the population, consolidated power for himself and cracked down on dissidents/party criticism.
The 2014 bit is more subjective, but going from memory that's when I started to regularly see semi-mainstream technology, business and politics publications focusing on problems/concerns with China.
