Honestly I think the whole "we are a startup search engine company who decided to spend the time to set up a production chain for t-shirts" is a worse use of resources than the actual money spent.

We are only humans, and we have a mountain to climb. Setting a base camp to pause and reflect on what we already achieved makes climbing that mountain more, not less, likely. Besides, there is no rush. We might as well enjoy the journey.

The shirts probably won't fit people that well. It just seems like a waste of time/money that nobody will really see value in (I'm a paying customer btw). But if it's more for "you" than the customer then that is a better way to frame it.

Well, at least it wasn't drugs.
