I think of "users don't care about decentralization" as being similar to "consumers don't care about what's in their food"

I work for Ethereum at the Ethereum Foundation.

I really want to understand your point 

If users care about decentralization why Tron become the #1 chain in payments?

I have no answer for it

personally I think the term "decentralization" confuses as often as it helps because people define it very differently - sometimes it is a stand-in for a specific objective ("capture resistant" or "permissionless"), other times it is a description of a design pattern that tries to achieve those objectives, etc.

The market here is "payments" not "chains". People choosing to use Tron (instead of trad payment rails) shows they do value some of the immediate benefits of "decentralization" (e.g. open global access). Other benefits of decentralization (e.g. resistance to capture) take time to show their worth.
