I think it’s a possible change, It will bring a lot of newer people that rather haven’t researched or want to move away from ‘main stream’ platforms to be able to come to the Fediverse and could be really possible for the amount of people being able to interact in general across both platforms.
It would also allow me to move away from Threads and stick to one account for most of the Fediverse based Social Media usage, and I really hope other Social Media’s follow in METAs steps.
It’s not a bad thing, gives you the option to read them on the Fediverse and it proves that the Fediverse could possibly be the future of Social Media. It’s good to see other people want to see it grow.
If people don’t like it then personally block it, the only reason for blocking a whole instance, instance wide is if it has morals that conflict to much such as a Anti-LGBT instance vs a LGBT one.
