I'm against the new logo due to readability and aesthetic reasons, to the point where I had to take actions once I saw how it looked in a browser (I'm primarily using the saidit app) because it was distracting.
To remove the new logo in your browser when visiting saidit.net:
Download and install uBlock Origin to your browser (if your browser doesn't support extensions, switch browser.)
Either press the pipette tool and select the elements you want to remove (It's pretty straight forward) and 'create' or add the lines
to "My Filters" under advanced settings.
So far I've found two places where it's prominent, the header bar and text posts in the feed.
If you play around and hide elements you want back, you can remove their entry from "My Filters".
