This is because companies buy long term contracts, which are still priced higher than the spot price on the, IMO reasonable, assumption that gas prices will rise again next year as the war continues (and Russia has more options to escalate e.g. cutting TurkStream).
Why would they cut (I assume you mean turn off, not blow up) Turkstream? Did you see the recent dealings between Russia and Turkey to expand those gas transit routes via that direction?
