If a company invests 5K in QTP I would make them use it! It seems kind of nonsensical to spend that much money on a tool and then move to a free open source tool when they find out its too cumbersome to operate or learn.
The best advice is to do your homework before you choose a tool. Remember there isn't a one size fit all automation solution; that doesn't exist! Well, I must admit, Selenium does come close to claiming that prize in the web space!
