I understand what you're saying, but I don't think you have anything to lose by forking away from ASICs. I think it is pretty clear that the net benefit of forking away from ASICS is higher than the net benefit of keeping with ASIC algorithms, especially if the focus is on decentralisation.
What is the net benefit of forking away from ASICs?
The anti-ASIC crowd seem to think that GPUs make a coin more decentralized. While there are millions of GPUs out there, it's naive to think that many very large farms don't already control large percentages of those GPUs... and thus hashrate. Pools make the "decentralized" argument even worse.
I argue that just changing parameters of a coin to make it harder for an ASIC to mine it leaves the coin vulnerable to 51% attacks. ASICs don't solve that problem, but they do make it harder to rent the power economically to make a 51% attack.
Back when there were no ASIC Equihash miners, you didn't hear anyone in the community saying 'you should fork TO an ASIC algorithm!', while now there is plenty of support to fork away from an ASIC. The community sentiment is clearly in the direction of less ASICs and more mining decentralisation

The "community sentiment" is made up of GPU miners who want to preserve their advantage.
I bet if the Zen voting system was implemented tomorrow and you had a vote on this issue, you'd have a pretty clear result in support of GPU mining.
You are probably right... but I don't know if GPU miners have thought this through.
But if you wait too long, the damage may be done and perhaps through ASICs/Bitmain, Zen ownership may become a little too centralised and who knows what the outcome of the vote would be.
ASICs and Bitmain are not the problem. They provide more efficient tools. It's like blaming a company that makes very sharp knives for cutting your vegetables too well.
I'm still of the view that Zen in many hands is the best way forward to increase adoption. As a side, this is another reason I really didn't like the Binance Zen listing competition, which required some like 30k USD in Zen purchases to be close to being eligible.
ASIC miners and Bitmain do not stop you from buying Zencash.
