Good work to those who wrote it.
If you have a better contract in hand then yes you should probably quit.
With that being said however if you leave on bad terms and your next job asks to contact the manager from your previous job the would probably say that you left on bad terms and might ruin your reputation.
for me i speak differently and write differently
writing: i do not use capitals or p unless i force myself to type a capital letter or punctuation
speaking: when i dont pay attention i use "!" and "null"
