Essentially, Twitter should have a clear and consistent moderation policy. Musk should not be able to arbitrarily change that policy, or certainly not when the situation directly concerns him. So you publish a policy and then it gets regularly reviewed, and that’s it.
Tbf, it seems that pre-Musk Twitter was also fairly arbitrary, it’s just now it’s for his benefit rather than the murky hidden incentives of the previous regime. They do seem to have set precedent by responding to arbitrary pressures.
