Well, that choice has already been made for them...
They could also choose to not buy anything at all. The merchandising team has always controlled the choices of what anyone buys for any show in the first place.
there is so much surrounding us that we could - and should - be using that outrage for.
Like the loss of a t-shirt option?
Here's the thing...the outrage stems from how easily the line could be taken out of context, when it is displayed completely out of context, as leverage for anti-trans activists. The marketing team realized this and thought it in the best interests of the show and the trans community to not distribute it any further. They probably envisioned a bunch of MAGA-hat bigots wearing shirts with that sentence holding "Get the trannies out of MY bathroom" signs (or something equally offensive and ignorant) and thought it looked like something Faux News would use as a screaming headline stating that BROADWAY was being HYPOCRITICAL because TOOTSIE THE MUSICAL sold TRANSPHOBIC T-SHIRTS. Because sad as it is, these days, that scenario is ENTIRELY PLAUSIBLE. But if one needs to wear that specific phrase on their clothing, they can print it on their own t-shirt (for probably a fraction of the cost). Problem solved.
But God forbid collectors don't get the shirt they saw but didn't buy, but might want to buy later because...I don't know. For whatever reason, Rent stopped selling the fantastic Today 4 U t-shirt shortly after it won the Tony and it never emerged again (the Will You Light My Candle T-shirt stuck around for a few months more, however). I didn't get the chance to buy it and somehow, I survived. I was ROBBED of my choice even if I never knew the reason why and I completely forgot to be angry about it. I guess people are only angry about this because they know the reason why, but it isn't a good enough reason for them. Or something.
