I coincidentally came across this post here: https://www.reddit.com/r/homelab/comments/7fkxr1/why_isnt_vyos_more_prevalent/dqdyc6j
When I checked https://vyos.io/ for a donation link I couldn’t find one which I found confusing when I on the other hand read that there’s not enough funding for growing the development team, etc.?
Have you ever considered using something like https://www.patreon.com/ ? (I don’t endorse the company, just the concept) It would allow recurring donations from very tiny to big amounts. While I personally wouldn’t be willing to donate a lot for what I currently use VyOS, I’d be fine with a recurring donation of 1$/month and maybe many others as well, companies maybe even more?
I know that this donation model allowed this guy https://www.patreon.com/objective_see/overview to invest more of his time into his open source tools. Sure that’s not full-time but already start.
For bigger undertakings, kickstarter like funding campaigns could be an option.
Just thought maybe this could be an interesting approach for VyOS, too?
