You can leave cold brew in the fridge and it’s ready when you want it. For hot drinks, you need to heat up the water, so that’s extra time between when you decide you want tea and when it’s ready for consumption.
Counterpoint: I actually like cold drinks quite a bit, e.g. cooled-down coffee with lots of cold milk, but I rarely have the patience to actually plan for that.
Pretty funny to complain about how long it takes to boil water when it would take way longer to cold-brew tea.

You’re assuming they’re doing a good job making cold tea and not just drinking lightly flavored cold water.
