The loss of the forum like help threads will probably be the most impactful thing. We can build communities elsewhere, but the 8 years old post about a problem only you and the OP is having is super valuable.
I am so happy to see people coming together and moving away from commercial platforms. It feels silly to say it, but it seems like it is a step in the right direction. It is technological and social progress. Decentralization is a really fantastic tool and it seems to be a system that cannot be controlled internally or externally. Mastodon has been great, and I expect Lemmy to be even better.
To anyone reading, if you have any extra cash, look into making a small donation to your instance. The people running it are not just putting in time, they are likely paying hundreds a month to rent server space.
This is great, many more subreddits should do something like this. But in the end, it’s us, the end users, who should do the actual protesting since it’s us who have the power to change things. I’ve decided not to give them any kind of traffic from now on. Me, by myself, won’t make much impact but if more of us did the same they’d be force to change their strategy.
the only thing that's worrying me about the subreddits closing indefinitely (even though I wholeheartedly support it), is that people are going to use even more closed off, unsearchable platforms as alternatives. /r/unixporn mods say their only "official" alternative is currently their Discord "server".
edit: the message on /r/iPhone also directs people to their Discord. sigh.
I'm glad some subreddits are going dark for good, not only will this actually hurt reddit as a company but also it will lead to some people switching to alternatives like lemmy which is always a good thing.
