Treating this transfer of WETH as just 'money' is an overly simplified model that is going to get someone burned in the same way as this reddit user. You are interacting directly with low level APIs that are irreversible while sending a lot of money to them, without knowing what they do. This is NOT good, and believe anyone without thorough understanding of these risks and how ERC APIs work should NOT be doing this.

There is an absolute need for cleaner UX on top of this with assurance/insurance to avoid this scenario (both of which exist and are being improved regularly). In the same way you don't directly interface with SWIFT APIs when doing bank transfers, you should not interface directly with ERC20 approve/transferFrom APIs in Ethereum, unless you really know what you are doing.
