I guess the operators of Nanopool are really good guys deciding not to do a double spend attack on the network while having more than 55% of the total hashrate đź«
Why don’t miners want to use the P2Pool even though it strengthens the network and also has great incentives like zero fees with a very low payout threshold?
Having 55% of hash doesn't mean you'll make profit by attempting a doublespend. I don't see how you could gain more from one and dumping the assets price + your reputation as a pool than by just behaving and passively collecting your fees forever. Nobody event talks about how 1 or 2 pools control 70% of zcash hash (although that's probably because nobody uses it) and even BTC has 2-3 companies (not even proper pools) controlling the majority of the hashrate.
It sounds scary but there really isn't that much a non-malicious, profit-driven pool could even do. Even a malicious pool could at worst mine empty blocks for a while.
It's definitely not ideal though, P2Pool is right there.
Very true. I am sad that p2pool only has so little hash :(

But a pool could be turned into a malicious pool by an adversary that takes control of it. A clear disadvantages of centralization is that it creates a single point of failure.

Why is this the case? I still have not studied the Monero protocol yet.
Shorting Monero and then attacking would most probably be the most profitable.
I doubt anyone could be that certain his attack will work. Especially mining on a public pool, it is likely destined to fail.
I'd hazard a guess that botnets and cryptominer worms cause the uptick in network hashrate for the centralized pools because it's easy to point hundreds of thousands of machines to 1 large pool.
Either way, it's not great.
Do nanopool users know they have a majority?
No way to know that.
