He was denied this without explanation, essentially forcing him to watch and move along with the WoL throughout Shadowbringers after 100 years of being a lonely shade, not allowed to return to the lifestream.
Yes, he offers himself willingly in the end, but there's quite enough there to argue that he was forced to do it as his only other choice was to let the WoL die. This is more or less coercion by authority. Ardbert's volition was disregarded 100 years prior to SHB.
And this particular story beat saw most of the playerbase coming to exclaim that the new expansions should feature us going around to the shards, gobbling up Azem's other soul shards, shard people be damned.
