I can. Because developers also need to pay their rent.
If every single piece of software was free, who would finance it? Most Linux developers have some kind of paying developer job and their contributions to Linux are on a hobbyist basis. And some Linux distributions cost a lot of money, charge a lot for support, and so on. Are you aware that Microsoft is one of the biggest contributors to the Linux Foundation? Also Oracle? Now, if we all stopped purchasing MS products and that money was also gone....
I contributed to Linux years ago (AoE), got €0 for it, but worked at a company charging for software and my employer was OK with "wasting" some time on Linux code. Who are the top contributors to the Linux codebase right now: Huawei, Intel, Red Hat, Google,.....who don't work for "free" or for altruistic reasons.
Hold on, and forgive me if I seem to be putting words in your mouth. First, you seem to be suggesting I have some duty to help developers pay their rent. I do not. I pay for it and that is all I am required to do. BTW, MOST Linux Distros are free. This is simply a fact.
I agree, many contribute and support Linux. Does not change a thing unless you are a conspiracy theorist.
When i say I refuse to pay for subscription software, let us be clear. I am not suggesting I would steal it. NOT that you are saying I do or would. I can get by with free options because they suit me well, for now. When I move to a new Mac, I'll still use free software.
Second, you say "If every single piece of software was free, who would finance it?" Well, I am certainly not suggesting that every piece of software be free. I've worked in the business in one way or another for many years, and I know a little something about how hard it is to write great code. I am one of the people that brought you your Palm Pilots, Newton modems, PCMCIA cards and RIO MP3 Players. Not a virgin, here.
I was also a database developer (Access and Fox Pro) and I wrote test software.
Now, the simple fact of the matter is almost all Linux software is free. Not only that, it is a requirement that the developers (in most cases) also provide source code. MS/Apple/most others would never distribute their code. We have a saying: Free and Open Source. And yes, the devs have other gigs, but that said, the software is free and they designed it to be free. There are very few exceptions to this simple fact.
Anyone here can download one of the 600 plus different Linux distros along with a dozen different desktops.
I am not necessarily faulting Adobe for their business model; I simply refuse to play until I have to.
