I do find it ironic that in their announcement, they don't even try to defend the decision, but instead say, effectively, "if you don't like this change, you're just bikeshedding", and "if you don't care about syntax, great!" Given that the entire purpose of Reason is one giant bikeshed about OCaml syntax, this reads as hypocritical.
They also say, effectively, "no complaining in public allowed, just PM us (so we don't have to have a real conversation and we can ignore you)", so you know they're great at working with their community.
