Yes, I agree (many will assume incorrectly).
Now consider, if you had a high STEEM wallet balance, say $50,000 and you incorrectly used the steemit logo and a lawsuit was filed. They'd know how much money the defendant had prior to the court case. :)
This will be one to watch for. I would like to assume that they're not wired for aggressive litigation and would rather seek amicable settlement limited to breaches of proprietary rights where damage to reputation or income was concerned.
But I prefer not to assume much.
Interestingly, while my browser tab still shows the old logo favicon the new logo favicon clearly can be accessed:
https://steemit.com/favicon.ico
Must be a cache thing, even though I've restarted my browser several times in the last 24h.
