How decentralized do you like your decentralization?

What is your personal definition of decentralized/decentralization?

Most dictionaries say when control is in the hands of two or more entities it is considered decentralized. Centralized would mean all the control is in the hands of only 1 entity. But I see people complain all the time on this sub that X isn't decentralized bc it only has Y number of decision makers.

So what does everyone think about this? How many entities are needed for something to be considered decentralized? 2? 10? 25? 100? 1000?

Some examples for clarity; Would a Blockchain with 1000 nodes be considered decentralized? Is 200 governance token holders enough for decentralization? Is the internet decentralized with 16 Tier 1 global networks?

I know it's a complex subject, but spit out some examples if you have them.
