Sure, you’re still using fossil fuels in that case-- for a few hours or maybe a few days a year, not every single day forever.

I can’t answer for OP here, but the explanation I often see on Lemmy is “poisoning/messing with the AI web crawlers”

I have to disagree. Not when they didn’t pay any taxes or tolls to build or maintain the bridge, and the bridge has signs at the entrances which state that it is still a completely volunteer-maintained project. Doesn’t matter how good the bridge is, or how many people have deemed themselves deserving of only good results, or that they don’t bother to read the signs. There is no level at which “ok, now they are entitled to trouble-free outcomes”.
