The future of Foss is in corporate time donations for projects that are useful for them. Open software collaboration is one hell of an efficiency gain. Whenever me or my colleagues have dead time I ask them to work on improving open source projects. It’s just a few days every few months but it adds up. Also we like to fix bugs in Foss software that affects our customers as we usually fix and upstream them and can bill that to the customer. So the company gets played, the worker gets payed and open source gets funding. No more sole maintainers for life that don’t have money to heat their homes because nobody donates. :)
