Why would you not be very clear about this right at the start of the interview process so you’re not wasting everybody’s (including your own) time? If this is one of your absolute show-stoppers, then say so up front and we can either work with IT to get you what you want, or decline and move on to the next candidate.

You have a lot more negotiating power once they give you an offer because of the sunk cost.

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 They rescinded their acceptance as soon as “IT specialist” told them they only officially support Windows.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.

They didn’t even attempt to negotiate.

you’re seeing a snapshot of an entire interaction between multiple people. you can’t be sure there was zero negotiations.

besides, you can’t even be sure any of this is even real.

keep your unfettered outrage bottled up for something else, because this ain’t the one for you.
