my first open source experience was thinking i knew better than the mana world devs about something and just screwing things up. i dont blame them for being standoff-ish as the internet is full of teens who got up one day and said "i could build my own MMORPG. how hard could it be?"
i have my own reasons for avoiding open source (ask me about them!) but i hope your experiences got better
