This. I’m totally for FOSS, but among four commercial apps that I use (SublimeText, SublimeMerge, Reaper and Bitwig), all four use this older model. You buy a period of free upgrades, but you may keep using the current version as long, as you wish. I see this model as beneficial for user and the company (providing them with money), but also encouraging it economically to continue developing the product. In the case of subscription-based model, I see little reason for the company to improve the product.
