I was a RedditIsFun/RiF user when I was mobile but mostly I was a keyboard user on a laptop/desktop.
I was losing interest in Reddit over recent years due to the mobile user influx (terse posters, lots of memes and TXT-speak) but thanks to the last few weeks, I have lost nearly all of my interest in Reddit.
I'm really not a joiner or a protester -- I'm rather pragmatic about all of this stuff. But the fact is that Reddit Inc. has by its actions alienated the users most responsible for making Reddit a thing that I enjoyed. It is already to late to recover from that.
Reddit Inc. could do a 180-degree turn today and it won't matter much. In the rough-and-tumble of all of Reddit Inc.'s self-inflicted nonsense, the users they lost (the heart of Reddits culture and spirt) have discovered life beyond Reddit. It looks doable. A month ago, that was fairly unthinkable. Come back? To what? The main reason for Reddit being compelling to me won't return, leaving behind a rather less-interesting Reddit community. I doubt it will attract me.
To me, this just shortened Reddit's long tail. Reddit was already dying a slow death, but this nonsense has made it faster. My current usage is now a small fraction of what it used to me (I have 100 MB of comments and posts submitted over the past 15 years). My guess is that there will be little left of interest in much shorter time span.
