I own two of the cans discussed here. Trying to help you guys out..rather than following up on what I suggested, it appears having something to rant about has more value. No $10 purchase needs to be made. The spout doesn't have to be stored inside the gas can(I agree..that's a pita, but it isn't necessary) and letting the vapor out of a heat-bloated can doesn't blow gas droplets everywhere..I just released the pressure from a can a few minutes ago..no mess..no drama..pretty uneventful.
The adjustment takes less than 2 minutes, takes virtually no tools(a dental pick or small screwdriver), it's free...look it up...or rant away..whichever makes you feel better.
