This response is mainly comprised of ad hominem and appeals to authority. The developers of Core should not be the people that decide on the future of Bitcoin. It should be the economic majority instead which is best reflected through proof of work. Saying that the miners have to upgrade is not the same as them actually voting with their hash power.

Furthermore Bitcoin Core is under the control of a single person, Wladamir does have the final say on what gets merged or not after all.
