Probably when people start actually not being able to use their apps of choice they will more seriously consider switching. Especially since apparently one of the Reddit apps is being ported to Lemmy, will probably take a lot of users with it.

I think most people still on Reddit are just trying to see how bad it actually goes, with the hope that maybe it won’t be as and as everyone says it will be. Platform inertia is very strong with any social media and the majority will not be easily convinced to switch to anywhere else.
