Also, it pisses me off that they're trying to revive thorn without doing the same for edh (ð), yogh (ȝ) and ash (æ). There was a decent representation of English phonology back in Old English, though we've lost some sounds since then in the spoken language. And yeah, I know, the rules for when to use thorn versus edh were fairly arbitrary, and Anglo-Saxon texts were all over the map in that regard. Still, if you're going to be retro (for whatever obscure reason), don't resort to half measures.

That’s their stated reason though.

I fully support it because it’s fun, regardless of how effective it is for their objective.
