Probably. However, anything could happen as everything is driven by greed nowadays. If Bitmain sees Bitcoin as the perfect opportunity to expand its profits over time, then they'll do whatever there is in their disposal to centralize the pioneer cryptocurrency for their own interests. Even worse, if the Chinese government starts pressuring Bitmain to attack the Bitcoin blockchain, it could successfully do so since it owns more than 51% of the total hashrate on the network. Nowadays, many people aren't concerned about this because they only care about making money with Bitcoin but not about its future and longevity as a currency for the enjoyment of everyone worldwide.
As soon as the negative effects of centralization are experienced in Bitcoin, then you'll see everyone worried about it, but it'll be too late. That's why I believe that developers and the community need to work together to help decentralize Bitcoin's mining process. By changing the PoW algorithm to an ASIC-resistant one, or simply devising an algorithm which makes mining pools useless, Bitcoin could achieve greater decentralization over the long term.
Nevertheless, Bitcoin is still considered as a decentralized cryptocurrency as it's open for anyone to join it. However, it's not as decentralized as it used to be in the past, since Bitmain has taken control of the mining process. Only time will tell us what lies ahead for the value proposition of censorship resistance within Bitcoin's blockchain. Just my thoughts
