It can force those who disagree with defederating to find a new instance that has access to all the communities they want. It also makes onboarding new people significantly more complicated, as their choice of instance will drastically influence their feed.
To be clear, I’m not arguing against defederation, just pointing out that it causes issues that need dealt with.
Playing music. Started on a shitty hand-me-down acoustic guitar. Got a better guitar. Got an electric. Got a better amp. Got a couple of pedals. Got a better amp. Got like 6 more amps, some cabs, 5 more guitars, a huge pedalboard, a cello, a keyboard, an audio interface, attenuators, mics, etc etc.
You gotta understand… I need all this stuff. There are subtle differences that you’ve never noticed before but will probably hear once I do an a/b comparison for you, and I absolutely must get an AC15 next to round out the collection instead of buckling down and recording something.
