In my experience, such arguments don't move the needle on adoption. "Hegemony" of a specific useful product is a concern to such a small number of people that even getting 100% of those people who are concerned or could be made to be concerned to use an alternative will not make a dent in the "hegemony."
The only thing that I have seen work is shipping a better, cheaper, and more useful product and focusing marketing on why a user would prefer to use it on its own merits. Everything else is preaching to the converted.
