Collaborating my ass.
Not to give these guys a pass, at all — this is some seriously skeezy marketing — but I think this underscores a deeper issue of paid accounts on Wikipedia, which is totally a thing as I found out recently. Apparently there people, or maybe a whole ecosystem, who are essentially lobbyists who get paid to edit Wikipedia pages, and that's okay, as long as they mark that they're a paid account, or something.
I guess if you follow Wikipedia's rules for paid accounts, it's okay to update pages in favor of your brand?
