That's obviously a subreddit local rule and as the message said doesn't target dedicerad instances, but social media links in general. I dunno why they do this but it's a pretty uncommon rule I think
OP mentioned having ADP and automatic backups enabled and I believe iCloud sync uploads photos continuously. The biggest risk is as you say battery saving and if it will upload data over mobile data (should be a setting for that).
Further than that I would say the big question is if someone else would actually be able to access the data if OP is detained.... and of course https://xkcd.com/538/ (I don't think the random chuds in ICE would have the know how for any technical bypass)
I'll admit that I'm not that updated on recent changes but reddit used to be open about the vote counts being intentionally inaccurate. I believe this at a point started to include scaling the vote count so that the average popular post would have 10-20k or so up votes, even if the actual vote count would be much higher.
So this would make it almost impossible to make any meaningful conclusions from vote count / active users alone.
I have heard a lot of people complaining about deleting the Local copy.. It seems to mainly be a bad faith argument where deleting the Local copy just refers to the process of freeing up local storage of unused files(?) repeated by people who doesn't actually use OneDrive but want a unarguable point to why it's shit.
(Mind you I think it's bad enough that Microsoft tries to kind of coerce you into handing them your data)
Eventually but I give it at least 1-2 years more. Too much big money has been put into this and they won't just let their investment die without a fight
Wouldn't blocking the sunlight for the grass be a problem?
Too many people seem too focused on getting 100%/Platinum though, and I feel like that's almost always going to end up in a kind of exploration grind, or just having achievements for playing the game.
The best achievements imo is when you do something random and get an achievement for it, then youll be able to see how many other players managed the same.
