Yeah, I get it. Whether the stated preference is honored in the end is an unknown. I'm just pointing out that it takes a special type of myopia to be unable to see the most prevalent and the only non Sybil-able indication of preference.
This works both ways btw. If some player change its mind and finally mine 2X despite what it announced,
1X could be in trouble.
Core's last node update to Satoshi:0.15.0.1 will reject all 2x mined blocks. Worst thing will happen is slow blocks and higher fees temporary. While the non-tech users having a chance losing there money because of missing out of replay protection.
Also, dont listen to Jbreher, he just a bigblocker who loves centralization while copy pasting all kind of stuff.
