Audience comment during Q&A at wroclove.rb 2023: an alternative developers tend to reject is learning sales and marketing and just selling software (as Mike Perham did with Sidekiq Pro/Enterprise). Donarski agrees it would help and cites Nate Berkopec running a Rails consultancy agency to fund his Puma work, but notes some maintainers (like Peter Solnica) prefer to focus on open source, making tea potentially a better fit — though perhaps 'too big a gun' compared to just shipping paid software.
