I agree with you about the dishonesty of saying yes (as I replied in another comment).
That said this is a choice you're making from what sounds like more religious reasons. Your company and your choice but it's not hard to employ TNs in a startup (and I know because I had TN status with two startups so I'm a little ahead of "brief reading of reddit posts").
TN status can also be applied for in advance by the way, doesn't have to be at the border. This wasn't an option when I had TN status but now it is.
While I was only speaking in hypotheticals about companies that only want to hire people who have legal status (no one has asked us to help them get TN status), I'd rather do zero paperwork by hiring people with existing status, than (allegedly) "not hard" work to support TN hopefuls, especially given the US government is liable these days to randomly change things around and cause chaos - especially in areas likely to score political points like immigration. POTUS could declare tomorrow that every TN (in a certain industry? state? whatever) has to go home in 10 days.
My attitude would certainly change though, if/when we can't find skilled people with existing work authorization, or if I had an incredibly strong personal referral.
