#2TL;DR no, but it will make it bitter and astringent because more caffeine and catechins will be extracted.

#4It will make it taste bad (bitter). It’s similar to overcooked pasta. Not ruined, but not good either.

#5I sorta knew this from experience, that high temperature would make the tea bitter. But why is this on HN?

It depends on the green, though. Good-quality green tea from China can often withstand higher temperatures or long brewing, to the point where it's normal to just pinch some tea in a mug and refill with hot water throughout the day.

#7All teas have "optimal" temperatures and brew times. A lot of green teas do not work well being boiled into bitter disappointment. Before I had to give up caffeine, I recall Gunpowder green tea being less tricky to get right. :)

#8the german tea expert Ernst Janssen recommends to also use boiling water to prepare green tea as most of the teas are contaminated with germs and other things. different green tea brands including organic tea brands were tested by the renowned German test.de magazine and they confirmed that, also most of organic teas are contaminated. and since this is nothing you can easily check at home, better use boiling water.

#9There's a lot of factors to it. The way the leaves are processed, the quality/freshness of the leaves, ratio of leaf to water, steeping time.
I think in general it's safest to brew green teas at 175f. But I'm doing quick gongfu brewing sessions with a late-march sichuan green tea, and it tastes great at 205f. Less intense at the usual 175f, but picks up more subtle flavors.

Because coders drink tea?
