Baidu has worse UX after google search exited the mainland china. The many so called newer internet companies are actually copying and localizing.

And with the help of ML, DPI is even smarter than before. Fewer people of new generation in China know Google, Facebook and Twitter, and they only know the second-class analogue of these service providers.
