Sorry, I fail to see, how a product that was developed from 2002 until 2017 proves that you lived through the 90's.

Tamagotchi

eMule was first released in 2002, as an open source alternative client to the official eDonkey2000 client.

Napster would have technically been a 90's term, since it released mid 1999, but p2p wasn't really a mainstream thing until the early 2000's.

I'll start my extensive poop tablet research as soon as my grant has been funded.

Google is not going to give answers that exist in forums and reddit threads.

That's a thing you said, and easily the dumbest thing I have read all day. Well, apart from almost everything else you have said, of course.

will not go out of your way to self crit and correct yourself if proven wrong

Sure, with that mountain of evidence you have provided to conclusively prove your point, I'm going to have take a nice, long, break from this 'discussion' and use it for self reflection.

Like I said, this isn't about personal preference, this is about general preference.

You can't tell me that "people with different eyesight, and who inexplicably don't want to use Android user profiles, sharing a poop tablet" is a larger subset of users than those who just want (and reasonably expect) the damn font size to stay the same when they switch Lemmy accounts. Right now, the app exclusively caters to the first group and doesn't even give the second group an option.

Now do that for 10 different Lemmy instances every single time you choose to change a setting ...

Wow, "Google doesn't index Reddit, Linux Forums and Mailing Lists" is a new one. Good job, I genuinely can't tell if you're a master troll or an giant idiot.

Regardless, as someone who has been active in the Linux community since around ~97, I'm at least certain that you are full of shit.

But I can say that our "bathroom tablet" that we can all grab as needed that has the fonts for my account set bigger, my kid's smaller, etc, it's handy.

Ignoring the fact that the "communal poop tablet" is probably not all the terribly common, why on earth would you rely on In-App-User-Profiles for that instead of Android User Profiles?

but having import/export as an option that will let you set up each account exactly the same if you want,

That might have been fine with one or two Reddit alt-accounts, but Lemmy is an entirely different beast. I feel like I'm instance-hopping almost daily for one reason or another and I'm rapidly amassing new accounts. Given how aggressively some instances defederate (I'm looking at you, Beehaw), there's little choice if you want to experience most of what Lemmy has to offer.

Suddenly, keeping all settings on these accounts in sync becomes a rather tedious and arduous task, which requires repetition every time one chooses to change their settings.

Compared to that, the edge cases where it may actually be useful behavior are ridiculously small. So, having this as the default and only behavior is simply bad design.

That's pretty cumbersome, isn't it, though?

Sensible per account settings certainly are. But these almost exclusively aren't, because they aren't really account-related settings.

My eyesight certainly doesn't change when I switch Lemmy accounts/instances, so why the heck should the font size?

Even if there were a genuine use-case for having different font sizes, themes, media-handling per account/instance, do you genuinely think that the vast majority of all users want entirely different app settings per Lemmy account and have them revert to their defaults each time they log into a new account, or would the majority just want to set these things up once and have them apply to all accounts automatically?

Per account settings, they way they are done here, would be a terrible default. As it stands, though, that's not just the default, it appears to be the only option.

If it's so famous, it should be trivial to gather a bunch of the more egregious examples of general update/upgrade breakage. Again, would you mind linking to them? I can neither personally remember them, nor is Google any help.

All I can find are minor, individual, dependency issues that are common with absolutely every Linux distro. I'm actually a little surprised how few of those Google digs up.

It would be rather worrisome if the foundation for an industry behemoth like REHL would commonly suffer from the problems you, and only you, are claiming without any kind of evidence. So, please, end my "delusion" and show me the error of my ways by showing us these common issues.

Are these issues in the room with us right now?
