Yes. This is our request / requirement for any mandatory dev fund, where the opt-out is “don’t run the software / don’t use Zcash,” rather than “run the software and decide not to contribute to a dev fund.”
By contrast, with a “miner’s choice” arrangement, the Zcash Foundation is comfortable with for-profit entities directly receiving protocol-based dev funding.
