They didn't even attempt to negotiate. They rescinded their acceptance as soon as "IT specialist" told them they only officially support Windows.

That happened to me prior, and I actually told them "hey, I really want this position, but you can't expect me to do it properly on the same hardware/software you give the data entry employees."

They gave me a budget to buy whatever hardware I want and told me I can install anything I want but I cannot reach you the sysadmin for any support outside of roles/permissions.
