At first glance I agreed, but I compared all the weapons and you'll find they have a decent balance now between weapon specific, universal, and utility based passives. I think their main point was specifically regarding why bow has been dragging behind and it stemmed from having too many eggs in their basket in the weapon specific department, all the other weapons didn't have that problem and as such worked as good front bar options even when you didn't have those weapon skills slotted.

Each skill line still has weapon specific interactions, that is a staple of the weapons. Bow still offers 25% damage done to only bow skills/auto attacks and now 2H gets a 10% buff to the weapon skills following a heavy. While strong before, it didn't have much interaction like the other passives in this list, especially when you consider the use cases. Heavy attacks are mostly for sustain in pve or stunning an off balance target in pvp where you would probably be spamming Wrecking Blow anyway. Now Wrecking Blow gets 4s of the buff along with auto attacks instead of just your 1 Wrecking Blow following a heavy. It's a nerf in some areas, but a big buff to 2H's playstyle.

If it helps, perhaps your character learned to use a bow from someone who trained with the Vinedusk. So you picked up some Bosmer archery tricks without ever having been to the place. Your character might not even know what their passive is called or where this knowledge originated from.

If only ZOS cared that much about Bosmer lore when it comes to stealth racial passives...
