Licensing comparison

Our competitors say that they have per perpetual or lifetime license, but we have a lifetime license for use and 1year of Free upgrades. Why our 4Team licensing is better? Because by selling upgrades you guaranteed that we always work on improving our software with each update and we have the best people for that. Can you do that for free? Still, if you decide not to upgrade after a one year you can use your license perpetual, just make sure that you have installation file stored in the safe place for the latter use.
