You must not have been part of the Digg exodus then. Because those of us on Digg that left, we knew the change was coming. Kevin Rose had talked about it. He gave some inklings of what was coming. The user base did protest. We did threaten. When they went ahead and went through with it, we left en masse for Reddit. Kevin sold the company, and gave information about what changes were coming. The community knew, and it was pissed. The only thing holding Reddit up right now, is lack of competition. If there was another site similar out there right now, a mass exodus would be underway right now. Mastodon, lemmy, all that stuff, doesn't count. It's not a real competitor, and neither is discord.
I wasn't part of the death of Digg, no. I don't really partake in social media much, so I was merely a witness to it as I noticed the noise coming down the grapevine via avenues like Slashdot.
You also kind of backed up my point; Reddit is way above critical mass right now and unlike with Digg that mass doesn't seem to be moving out anywhere. If these strikes and demonstrations want to make a difference the actions taken need to be far more drastic.
Real world worker strikes have a potential to work because the workers are willing to put their employment on the line, an ultimatum. What's happening on Reddit right now isn't an ultimatum; users aren't putting their Redditing on the line. Two days to a few weeks of privatisation is something Reddit can weather just fine, even moreso if the subreddit itself is still readable as in the case of some.
