If I remember correctly, Reddit's app was first on the IOS App Store before the whole API debacle. So we can assume that a significant percentage of users are using the official app and being brainwashed by Reddit's ads to keep the shareholders happy.
They wanted to bring the rest of users into the fold. It's good to see that so many didn't and came here instead.
As long as there’s enough of us here to establish a community of our own, we can easily make a positive space for ourselves while the scrollzombies left on Reddit can stick with their collapsing website.
It's a tiny migration to be fair. I seem to recall that the number of Reddit users using third party apps was very small. Most Reddit users haven't been affected by the change.
Percentage doesn't really matter. A very small percentage of redditors actually created content or commented. So if most of the "small amount" of users who left were mostly content creators and commenters that would be extremely disruptive to the site. Lurkers don't matter when it comes to user numbers.
It's hard to get hold of precise statistics but most (honest) attempts at quantifying it end up at around 10+% of total Reddit users. So we're potentially talking 10s of millions of MAUs (monthly active users).
Definitely significant when compared to current Lemmy numbers
Well, Lemmy has well over 2m users at this point. I expected lots of the larger ones to get hit harder than they did as well, especially because per instance, lemmy only scales vertically. There’s also no cache to my knowledge
