Yeah there is downfall in the users and post on the Indonesian board with a difference of 236 post this time and active users have also gone down with 5 which can be due to the reason you have mentioned above as many are writing for the campaign requirements only and if they didn't feel incentivise for it they lack the motivation to contribute but they should Focus more on having healthy participation with their local members.
Yes, the reason is true but I think their participation in local board is not mandatory but only awareness. Several times I have suggested that they are expected to be willing to do something for their local board regardless of whether they want to post or distribute merit, it's up to them. But some of these downward looking statistics shouldn't be a big deal for local board, but yes statistically it is something.
