Calling for a boycott won't accomplish much. Trying to throw your weight around because you have some computer hardware doesn't really seem like an idea many people would follow.
This is just like when Bitcoin had ASICs designed for it. It is an inevitable conclusion, and perhaps the coins you mentioned will have market cap drop because of their decisions when GPU miners need to mine elsewhere to try and get ROI after getting beat out by ASICs.
This is why you should understand the risks of mining and difficulty rising.
if you believe in all asics and no gpus you are mistaken
gpus allow as much 1billion miners .
as 1 billion pcs with a decent graphics card will eventually exist.
to shut that out is bad business.
why make a billion customers located world wide go buy buy?
Al-gore-rythms can be forked every 2 months if need be that would stop asics.
read my signature and you will understand why all asic world = fail
