When I started work engineers has $10k RISC workstations and $50k/year in software licences, we did external training regularly. We were expensive, and mgmt were loathe to waste our time on crud because of that, and because we delivered. Now they talk about cloud synergies and ITIL processes and outsourcing and tech partnerships -- tech costs WAY MORE but devs/engineers aren't seen as delivering value. No one pays anything for the open source that makes it all work. It's enough to make you want to run away and join a startup.
I enjoy being paid to develop software, so I also want the producers of my tools to be able to pay for their bills.
I wonder how may that use FOSS on their business actually pay/donate anything, even a penny, to the developers.
My experience consulting says pretty much no one.
