I am not a fan or the "rental' system either, but from a producers point of view it's a no-brainer. You keep a steady flow of cash coming in. You get to make updates and tweeks, so that some flashy new product from a competitor doesn't look "way better." And you can keep up with the latest in cyber security. --- Before when people were buying new computers and upgrading their software every year or two it didn't seem so necessary from a cash flow perspective. --- You can see the reason on this thread; making do with things 5-10+ years old is not a good business model.
