This is the main source of all problems. People stopped caring about a lot of things and forgot what mattered. We keep seeing it in different topics like the Ordinals Attack which many falsely said preventing this abuse is against censorship resistance.
It sometimes feels like people nowadays just want Bitcoin to exist and its price to go up. Nothing else matters to them.

Here is an example. Just go back 5-10 years in topics and see how people were concerned about mining/hashrate concentration in China and how that was a potential threat. And that was during the time when Chinese miners were freely mining without being forced by the Chinese government to attack Bitcoin. And that's an important distinction.
Today a lot of hashrate is concentrated in the USA and the US based miners are ordered by the US government to attack one of the main principles of Bitcoin by censoring transactions, and yet nobody is concerned about it! You don't even see any topics on this 24/7 attack anywhere!

I dare say that it is not about the people not caring about these things anymore but it is that they don't even understand the problems to care about them!

In any case, Bitcoin is still the most decentralized payment system but centralization is slowly creeping in...
