This is exactly the wrong outcome. We have provisions for such uses, the Fair Use doctrine.

If this entry results in people deleting the logo, while they used it legally, this article has become FUD.

We shouldn't live, and react, because we fear. As @joshpeterson said, education is better than inactivity [paraphrased]. Any article writing about the redesign, with the logo integrated, will be covered under Fair Use. Even if your article makes money of it. Even if you write a design analysis of the logo only and tear it to shreds. In the latter case, having a similar content archive may help, but it isn't required.

What commercial use isn't allowed? Write a Steem news site and use the new Steemit logo in your own logo. That is now explicitly outlawed.
