it’s not about anger, the point of downvoting is to put low effort or other random crap comments below any others that may actually contribute to the topic.
it’s not too complicated to give people an elevator pitch. of course there is more detail and nuance to get into (as with with literally everything), but it’s not needed to get the general point across.
Well the general idea of federation is not the same as “fediverse”. most “fediverse” sites are FOSS which is the main selling point in my opinion. They cannot be sold and do not rely on ad income (and thus preying on people’s cognitive weaknesses with algorithms) to operate. Federation is an added bonus on top of that which allows you to set up your own instance if you want.
Sure meta could make a federated service of some kind (like bluesky has done), but without being FOSS there’s always the high likelihood of enshittification.
