Really liked the final comment.
I do still hold the view blocking them isn't the right answer, maybe its needless optimism, I understand the idea of meta developing it's own fork, but if you can already have this many people agreeing to blovk them I feel a condition could already be negotiated (like instances will inly federate if the code is open source) instead of blocking outright. I feel this is the nuclear option and there are still unexplored solutions.
Problem for me is that, I don't like an image of the fediverse where we just block any big service that comes our way, we all stand more to gain if we manage to get federating right, even if it requires putting up conditions for that federation to be done.
Also I don't think mastodon or the fediverse at large would not survive one of those services suddenly defederating (or violating the hypothetical condition, thus for ing everyone to block them), this is probably where my hopeless optimism comes into play, but the community already built here is pretty tech savvy and we are already at numbers capable of self sustaining, I feel the community would not die out if we loose access to whatever one of those big services was offering.
Still this federation shouldn't affect lemmy that much since it's geared towards mastodon like microblogging services right now, so I will stand by whatever this community decides.
