I do wish that some theme authors would not try to claim copyright of a user’s site. It’s not cool. The theme author has copyright of the theme they have created, yes, but not the site that the theme is installed and activated on.

“Copyright 2022 – Raft by Otter” is in the front facing footer.
It’s true that this can be changed by editing the footer template part, but it should not even read like this by default on a live publically viewable site, however easy it may be to edit.

Such a shame as the theme is genuinely nice with its attention to detail, style variations and patterns.
