This sort of happened when the WHATWG effectively wrested control of HTML away from the W3C (although Google was not a founding member, they are one of the Steering Members now). https://thehistoryoftheweb.com/when-standards-divide/ https://thehistoryoftheweb.com/when-standards-divide/ The membership of the W3C supported XHTML, to improve interoperability among other reasons. Apple, Mozilla and Opera had a different vision and broke away and formed the WHATWG which Google and Microsoft later joined. Those companies (minus Opera) now have near total control over HTML and the W3C just rubber stamps whatever they decide. (Note: I don't believe the participants in WHATWG were doing what they did for anti-competitive purposes, but in hindsight it had that effect.)
