I had to read it twice for what it's worth but to rephrase for them, they spent so much over the years on audio visual software for Windows that the total sum spent could have instead purchased them a quality used automobile. However if/when Windows gets worse they may eventually have to stop using the programs they invested a significant amount of money on just due to how awful the OS has become.

@supafuzz@hexbear.net is this an accurate paraphrasing for our comrades who have some trouble with indirect language?
