Hi Bart,
we as a company have an active product license. Originally (years ago, we're one of the early adopters) it was registered to me, but since we changed our process for software purchases, the owner (aka company) is not the user (aka my colleagues and me) anymore.
Apart from that, you as a company should be grateful for anyone reporting bugs in your products no matter if they have an active license or not.
regards
Lübbe
