that would be a lot more manipulative

I feel the opposite. I do a lot of work for free. If I don't set a price up front and get paid, I'm very grateful, but if I don't get paid after the work is done I don't feel put out about it, because I didn't state it would cost money up front. I do not think it's manipulative at all to state the pay for the work up front, and see no reason to claim it is.

You have done a yoeman's job representing Hive, and I feel your ask is justified. I just do disagree on this point, and feel very strongly you should state compensation for your work up front going forward. That isn't manipulative, but enables everyone to know what to expect.
