Yes, I knew that the transaction value (and source, sink) was known after processing it and putting it in the blockchain, just not that it was known by the miner processing the transaction before putting it on the blockchain - I assumed when "mining" a transaction that somehow the details would be hidden.
Them being visible seems to raise interesting attacks, such as an individual being doxed and then unable to have their transaction verified/accepted.
A sibling comment suggests Monero have addressed this.
Edit: If 51% agree not to process any transactions for accounts holding >$1M worth of Btc can they steal financial value? Like a stock buyback but you pay zero to the holder and get the stock anyway.

You have some fundamental misunderstandings in how bitcoin and bitcoin mining work. I'd suggest reading up on one of the links a sibling comment posted.
In the interim, perhaps you could clear up a couple of questions, as you realise I've not studied the process for maybe 16years (I forget a lot in that time). Are these true?
1) Those processing transactions know which wallet they belong to before they choose to process it (this was the surprise to me presented here).
2) Wallets can be linked to people as the blockchain shows wallet holding value and transactions. (State actors can probably correlate with bank transactions; people in general can learn 'oh John Doe bought pizza from me using that wallet').
