Vinegar is broken down in the soil but it also lowers soil pH in the process. It WILL kill pretty much all plant life in the process.
Angela is right though, the oral LD50 for acetic acid is 3310mg/kg for a rat. The oral LD50 for glyphosate is 5400mg/kg. Glyphosate is in fact less toxic than acetic acid.
Some (organic) vinegar may contain minerals that are useful to plant life, the amount however is almost certainly completely negligible.
Vinegar has been around for a long time but so has lead, mercury and cyanide. The natural world is full of deadly toxins. And everything is relative...
Now, I dislike the use of glyphosate, and pesticides in general about as much as you do but I do like to argue based on facts.
