Although an additional comment to say this won't please the people that hate turnips as an option, but it's clear to me at least you as a company value the rates and hours people put in, and are willing to accommodate and respect those things. No pushing towards turnips is being done. At all. No favouritism, no limited rlc slots. A company that is asking for rates doesn't have the responsibility to make an artist raise them, but without having actual communication via the application process, it's entirely possible that, being an artist, the dev would point out undervaluing. Speculative, of course, but so is the claim that those with a low sense of self value in their work will be taken advantage of.
Granted, at this point, offering turnips internally as an option for people to take on a project by project basis might be an option to chill the ones that are so against them as a choice out. Not that I feel it should have to be done, but a suggestion to consider if it's something that is concerning the team.
Maybe chill with the aggressive takes folks, they really don't offer constructive criticism. Wouldn't hurt to put your concerns politely, and not make assumptions without facts. Advice for artists does not need to be delivered with a plate of salt towards an option you don't agree with.
