That was just to point out the text-recognition engine can handle both English and Chinese in the same text field at the same time.

Showing features your customers would like isn't really the same thing as pandering.

Written Chinese is an incredibly difficult language for handwriting recognition because there are literally hundreds of thousands of symbols, and they are not all amalgamations of smaller symbols as you might be tempted to think. Showing support for Chinese is impressive.

Additionally, the speaker may have actually been learning how to write Chinese (it's not exactly unheard of), so it could have been a case of "We need to showcase this technology that support handwriting in multiple languages. Since I'm learning Chinese, maybe I'll use that!"

Not everything is a nefarious corporate-state conspiracy.
