I don’t drive these policies and I didn’t as a developer. I am an open source evangelist. That said anyone who tells you GiMP is equal to Photoshop or that inkscape is equal to AI is nuts. Both open source products are great but at the end of the day they still don’t meet the mark. Prior to the subscription model I used gimp a lot. The tools serve their market. As much as I love Photoshop I wouldn’t pay $400 for it. The stuff I use it for I can easily absorb $10 by the money I make selling images. My time is valuable to me. So I can take 10 minutes to mask an image or 5 seconds. A handful of images and I am way beyond a $10 value.
On topic with FreePBX. The project serves a wide audience. We see it servicing random solutions on a raspberry pi. We also see it running in large government agencies and Fortune 100s.
There is no Monopoly on the software by any given sector. Each sector has very different needs. Many of those sectors have only 2 requirements. It meet a budget and it JUST WORKS. They give priority to function over cost. We all know the base coat of a product is not all inclusive. People drop $10k on a feature equal product they can get for $500 because it comes with guarantees, support, training etc etc. I use to install commercial key systems. The office manager never sat on the phone with some random person. I was on site within the hour when needed 24/7. The business process made sure we put in a product that minimized that need. Most end users want to pay for something they don’t know they are using. If this means paying a premium to a reseller, or paying a subscription they will do it. People want a solution not a part time job.
Back off topic. I just dropped another $400 on a laser cutter. I don’t expect it to be a $3000 solution. I know it will take effort to make it perform to that level. There are a lot of people like me. There are a lot more that just drop the $3k and call it a day.
