The only way to accomplish this at scale is to build something that is legit better and let the market decide. Anything else is just principled wishful thinking.
Microsoft Teams "won" entirely because it was given away free with Office. Even though it is acceptable these days, it was horrible when it started. There is no way it could have won without unlimited backing from a bigger force.
You have to see EU trying these things in the same light.
JVC also licensed the VHS format to many manufacturers, so there was a lot of competition on recorders, further driving the price of ownership down. I don't recall anyone ever selling Betamax other than Sony.
Edit: JVC actually released VHS as an open standard, not a license, per Wikipedia.
