Ok, let me spell it out even more clearly than the 4 times I've already spelled it out:
When Anaris says,
"Yes - I am willing to work with you and other experienced devs to start using modern methods such as composer, unit testing, class-based code, etc and will be open to taking advice about how to refactor the code base, instead of putting up a wall of objections"
then I will volunteer some of my time and work to recruit other experienced devs to help with the site.
If he only wants people to sit and add more band-aids on top of this rickety old legacy code, then I have no interest (and I doubt any other experienced devs do either)
There's an unlimited number of Open Source projects we can and do contribute to. We don't have the energy to work on something where half the team is just breaking our code & arguing with us all the time.
