"For me, the answer now lies in refusal, the withdrawal of participation from systems that require dishonesty as the price of belonging."

Part of the argument is that one reason we don't find filter bubbles is that we've been looking in 2D

Encyclopædia Britannica will continue to use ‘Gulf of Mexico’ for a few reasons:

-We serve an international audience, a majority of which is outside the U.S.

-The Gulf of Mexico is an international body of water, and the U.S.’s authority to rename it is ambiguous.
