Day 1 Cisco

To prevent the potential of community spread of the Coronavirus inside and outside of the workplace, some companies are requiring employees to work remotely after international travel. Other companies, such as Twitter are asking employees to work remotely if possible, even if they are not in areas currently impacted by the virus.
Cisco is one of the first companies to react to this by offering free access to technology. They offer unlimited usage with no time restrictions for 90 days to new customers. This offer is valid in all countries where it is available, not only those impacted by the virus.
Off course it is a way to offer a taste of their free offering, hoping that you will become a paying customer once your trial is over. Anyways, this is a fantastic and very useful gesture
My question for you: can you offer something for free now and later convert trial users to paid customers?
