[unknown] This is why people object to your premium plan.
"Pay us money for our chapters, because the authors and translators need their cut," you say, and I agree; that is necessary and fine.
But then you follow it with, "But don't expect any regular release schedule or consistency, because the translators are only doing this as a hobby, not as a job."
If you are getting paid, it's a job. If it's a job, there are obligations. As a company, you should be enforcing the obligations of your employees, especially where money is involved.
This "pay us for our work and we'll do it at the rate we choose without telling you anything definite" really comes off as unprofessional.
