The issue is not necessarily the policy changes by themselves but rather the context in which they are occuring, the very suspicious timing, which makes it look like Zuck is simply catering to the newly elected President. That's the opposite of "free speech" and eliminating bias.

And the notion suggested by Zuck that Texas is somehow less biased than California is ridiculous. Perhaps if he had suggested a swing state like Wisconsin, for example (which happens to have some empty space available where a Foxconn factory was never built).
