I had this case too, in a very big company. They were very aggressive.
We put a ban on their products and the company was coming back for years trying to get a business, this case was always handy to send an answer.
The problem is not that they wanted us to pay for a few installations (individual decisions of some employees), but that they immediately went nuclear with legal, threatening us with the court if we do not buy an enterprise license for everyone. It pissed us off.
The funny thing is that we somehow discovered their products this way and should that just said "you have a few installs of our products, wanna talk?", they would have had a great deal with much more installs
