Given that Russia had troubles supplying gas via pipeline (remember the five NS1 pumps that failed and the sixth pump that had to be shut down?) and given that Baltic infrastructure is constantly being damaged, the more expensive LNG should be considered a risk premium. It's harder to attack and can be diverted in times of need, one of the reasons Europe got so unscathed through the gas crisis.

And if pipeline gas is cheaper is also up for debate, because gas is gas to the markets and the long-running supply contracts (which turned out to be worthless because Russia was suffering a conveniently-timed force majeure) had indexed prices.
