I might be the minority who was affected by this but how they handled the physical goodies last year was the last straw for me. Unlike all the spammy contributions that rush to it, I didn't rush creating some pointless PRs on the first day or whatever. My last PR finished its embargo period a few days before the end of October. They even sent out a congratulations email, but when I clicked the link and went to the website there wasn't anything there. Only when I checked their discord, I saw others with the same confusion and someone semi-officially saying they might've run out. It's obvious they didn't even ever consider running out and had no system in place to handle that.

Other than that, some of the rules they introduced in recent years were also so detrimental to meaningful PRs even though they thought it'd motivate that, instead of spammy PRs. Clearly that didn't work at all and actually had the opposite effect in some cases. It was a lot easier to get spammy PRs counted than meaningful ones.

I could rant in more detail about the latter if you're interested, but I'll refrain right now.
