The community is pretty skeptical:
”Someone should just fork gitcoin.”
“Sad to see Gitcoin focus on such a distorted US-centric view of the world”
”..real inclusivity is delivering L2 support so people who can't afford to spend 50$ of tx fees to donate can participate and show support to projects..” (during this round Ethereum gas fees are pretty high community highlights that L2 support is necessary for donations);
An article on PBS and how it impacts the fork choice rule by constexpr.eth and Georgios Konstantopoulos, summarised in a twitter thread by Toni Wahrstätter.
