Right now it's not even mastodon compatible let alone lemmy. There are some arguments on how federating with them will allow people to migrate to a more privacy respecting instance and still view threads content, and some users say this will allow them to still communicate with their friends who don't want to switch away from threads.

Yea some countries have strict piracy laws, that's why using a VPN and following basic privacy becomes necessary while pirating.
