Well, it's not exactly the same. It's not a forum (not that a forum is easy, but it's completely different). If you just substitute most Wikipedia editors, with no handover process, I assure you it's going to be a mess.
Well, they've mostly left reddit as well, afaik. It's a few stragglers, people being paid to push agenda, and auto-moderation now. I was reading / moderating reddit for over 4 hours a day, every day, for close to a decade. Heavy handed pro israeli censorship and propaganda has seen me pick up and leave, as i know many others have done. I was already wavering, over reddit's support of astroturfing and shill bots which were obvious, detectable, and reddit refused to do anything about it. Even actively supported it. So with the whole denying /actively supporting genocide thing, it was time to hang it up and leave.
If wikipedia is shutting off avenues for community input, maybe that is running it's course as well.
Its been nice internet, I loved you, and I will never forgive google for what they put into motion.
