I would say it is unavoidable; you can kick them off but then they will sign back on with something you cannot identify. I myself always try to communicate with them and see if there is room for cooperation. You would be surprised how much we got from that. Notably companies we thought were far more advanced (size, sale or feature wise) than we are and finding out they are not. And in one occasion we ended up buying them because they were incompletely over their heads and were trying our system to see if we had the same issue (we did not).
