What are "normal cooking temperatures," doctor?
And I'm talking about .3 g WEED not HASH. Average weed isn't anywhere close to even weak hash. It's a huge difference in potency. Your reading comprehension is pretty abysmal.
Since you're too lazy to google here's a couple of links you might want to check out:

Well, about 180c/360f/gas mark 4, that's around the temperature cakes get baked at & it's the same temperature that thc vaporises. Lower temperatures are fine - but they're 'low' cooking temperatures, not medium or high. If the oven is a bit too hot your space cake ends up bunk & cake doesn't seem the best carrier anyway. Boiling weed in milk/cream works, that doesn't get hot enough to vaporise thc usually & makes a good hot chocolate.
Make sure your fat gets nowhere near it's 'smoke point', don't let it start spitting or smelling. If you use butter or coconut oil, it's smoke point is a bit below the vaporisation temperature of thc, other cooking oils are higher. If you do cook it, the heat needs to be low. Mix it into something small & light, milk, cream & yoghurt hold it well.
The thread is about hash, not weed. Weed is a little harder to make into a successful edible than hash. Weed does need cooking a little bit to just get the thc dissolved into whatever fat, again a medium or high temperature will kill it. Hash simply melts & dissolves quickly with only a little heat for a few seconds, that's enough.
Your links don't really mention anything that contradicts me, except they seem to think you need to go to extreme lengths to decarboxylise, that's just not the case with most commercial hash, it's already done. They miss the point that THCa is going to be very unstable in dead, dry, plant material, heating is anything above about -20c, it reacts with light & oxygen too, it's only stable for 4 days at room temperature. There's just not going to be much left in any hash you buy, it will already be mainly if not all THC, unless you've had it prepared specially to get large quantities of THCa. With imported hash from some hot country there's no chance, it could be a year old & stored at 30c+ a lot of the time, unless it's the real cream of the crop. With black hash you can see it's oxidised, that's what the black colour comes from (unless it's some diesel or henna filled rubbish). There's a fair amount of friction with most traditional hash production techniques too. Lower quality hash needs some heat just to press it.
Trust me, eating hash works, especially if it's some cheap import hash which possibly isn't the greatest smoke, there's no need to cook it, just melt it in some oil & mix in a yoghurt or whatever, nobody wastes anything then & we get stoned as fuck.
I'm in England, I can't get hash here any more, it's all just locally grown hydro bud (which is all really top strength), it's all good weed, we have a high 'average', you'd be talking about strains like blueberry, super skunk, orange bud, etc for our average, it's all 15-25% thc stuff & the top quality stuff might be better than any you've seen. When we did get hash it wasn't always fantastic, it was always cheaper than local 'skunk' & then it turned into adulterated soapbar which is worse than the worst weed, that gave it a bad reputation with everybody & now nobody around here wants hash (except me). It'd be import hash, crumbly morrocan polm, or sticky black afghan/pakistani 'gold seal' mainly, nothing like the quality you can get with homemade hash using modern techniques, just barely strong enough to still be hash without being adulterated shit, or sometimes it was possibly a bit adulterated - I'd turn it down if it was worse than good hydro weed, but it's often not a huge amount stronger.

This is the kind of stuff I'm talking about, but it was still available to me until a few years ago -
