Consider that complaining to the company sometimes has an effect and results in a change in the product. A few years back, Intuit initiated a similar 'activation' function in their Turbo Tax income tax program. It created quite a storm. DH emailed them complaining about it, along with a zillion other customers - there were also numerous articles written in complaing of the activation feature (many felt it was also a privacy issue as it was a form of monitoring by Intuit). Intuit later backtracked, and stopped using product activation in future versions of TurboTax.
