I think the elephant in the room that some don't want to highlight too much is that the risk curve associated with poor collateral grows exponentially, while with years of market data, we can now confidently state that the yield curve grows linearly. Do you want to go 10-50x your risk to go bust for a marginally better yield (if any in many cases)? But why? Because most poor-quality collateral with any traction is a yield product, and they live or die based on whether looping them is profitable. If using them as collateral would cost 15/25% APR, then loops don't work, so they have to make up for it with extra incentives, "points," native tokens, and enough obfuscation to persuade you to LP. In short, some protocols are designed to make you the "Useful Idiot" counterparty taking the burden of risk to earn suboptimal yield, allowing the other side to extract more profits Just Use Aave.

The annoying part is that we are supposed to have all learned this last cycle with CeDeFi going bust, which used to offer marginally "better" yield. It took years of VC efforts, make-believe "Innovation", and subsidies to make some of the community forget it I guess
