@gamingonlinux will be very interesting to see with regards to federation. On one hand, it makes it far less difficult to follow and interact with IG users. No need for Bibliogram or other workarounds to an extent, and no need for an Instagram account.
On the other hand, I am sure a LOT of instances will outright block federating with them, similar I imagine to what some have said with Tumblr announcing AcitivityPub federation.
