I find that pretty annoying when I'm looking for tools, but I do think it works, with varying degrees of shadiness. Some companies completely rebrand a product as if it were custom-designed for an area, taking their Foo Software and making it Foo Software for Healthcare, when in fact that's a lie and it wasn't customized for healthcare at all (and certainly not based on any knowledge of the area or research into its practices). Maybe users don't notice, and even if they do, sometimes you can mitigate it by just giving refunds freely to the users who complain, and keeping the money of those who don't.

An even scammier version of that is to rebrand software you didn't even make, like take VLC and rebrand it as customized video software for $whatever, when indeed you've done no customization for anything.
