One thing I don't understand - why would exceptionally high or uncapped safes be a bad deal for founders? The post mentions that this leads to dilution and other issues in the eventual series A, but doesn't an uncapped safe lead to less dilution in the series A than a safe with a lower cap? Why is it a bad thing that there are more "to good to be true" offers being made now?
