While information is public on blockchains and everyone has same level of access to it, transaction execution is not democratized.

The premise of this whole reverse-exploit is that there are people who are extracting value by getting preferential treatment with their transaction execution by doing deals outside of the blockchain itself (which are hidden and not public by default).

Trading in exchanges doesnt happen in the blockchain though. But the exchanges provide apis to the order books and all the L2 data you'd usually pay $24k/yr for via a bloomberg terminal for the stock market.

Its specific to the kind of blockchain/DLT that it runs on. If you use an DEX that doesn't rely on miners who can pick Tx then you dont have this problem. For example the XRPL DEX does not allow any party to pick which order to execute. There is also no mempool where someone could look for bundles of Tx. A DEX order is, once submitted, added to the state of the ledger (added to the blockchain) and executed as soon as possible.
