Seems appropriate, given the function of the service

Open Collective is a superb service, bravo.

Author here. Spliit is a free, open source Splitwise alternative; donations cover hosting (~$150/month) and nothing else, not me or contributors.

Open Source Collective takes 10% of incoming funds as fiscal host. Worth it to me: donations no longer land in my personal account, and the ledger is public, so nobody has to take my word for where the money goes.
