Why would anyone assume that was some pseudo-trademark of codeweavers? It's not particularly clever and anyone could come up with it. I would've assumed literally anyone in the wine ecosystem could've come up with it and given codeweavers (nor anyone else) did not file for a trademark then that suggests they don't care that it was "ripped" from them to begin with.
My whole point of view is that there seems to be some assumption of malice or feelings slighted where there's no evidence that codeweavers feels slighted or that bottles was being malicious. I generally think the internet would be a much better place without assumptions of malice.
