As with most things, my opinion of Threads integration to the Fediverse is very nuanced.
On one hand, I enjoy the idea of being able to engage and interact with the wider social web. On the other hand, the sheer amount of Threads users makes me worry that Fediverse will soon be just like corporate social media sites.
I don't want to be lost in the mix of millions of posts, with hardly any engagement.
Also, Mastodon will be adding "limit replies" soon enough and that's bad for a number of reasons, the biggest being misinformation...😬
I am still VERY cautiously optimistic. However, if I start noticing my engagement fall off a cliff, I'll be immensely sad.😔
