Edit: not exactly decentralized in practice.
As a hypothetical example, imagine that Brave is sold, and new owners changed the code so that 50% of the tokens go to the PRESIDENT RE-ELECTION FUND, instead of the website user looks at.
Brave could make a new BAT token and point their browser to use it, but they don't get to do anything with the original code controlling the tokens everyone is already using. It cannot be disabled, modified, or deleted, by Brave Inc or by any person.

This by itself is strong proof of centralization. Brave can unilaterally make this change and give themselves total control over BAT 2.0 while leaving the original BAT worthless.
