It probably depends on both the market and the cultural landscape. I'm in the UK, and USA providers are more 'cut-throat' than domestic UK providers in my personal experience when I have tendered enterprise software in the past, and the cultural differences have been massive. Cut-throat is fine until you get a reputation for cost overruns, get to be known as untrustworthy, and eventually end up with a lack of customers willing to give you positive references. I certainly know which vendors in my industry are known for land & expand and scummy sales tactics (and when I personally see these tactics being deployed I will tell everyone else I know in the industry to avoid them like the plague).
