I mean yeah, probably they would know, but it wouldn’t hurt to talk to em. Either way, specific negative feedback from potential customers gives them at least a small incentive to change… not that it’d probably be significant enough to make a difference in this case. But hypothetically, if enough people did get upset about it and it hurt the business’ bottom line, I’d want them to know the reason.

If nothing else, at least they’ll know what the brick is for. ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯
