I can get behind that

Ohh the “what time is it in films” argument is good, haven’t heard that one before, thanks

It’s gonna get much worse when you start to try mapping days of the week onto the new times. Are days gonna be the same everywhere as well, to stay from 0 to 24? If so, have fun saying things like “Let’s find a time on Wednesday/Thursday”. People likely couldn’t be bothered and would probably just use the day that their normal wake-up time falls on to mean the full solar day instead. At which point you could also just say okay, weekdays are still following local solar days. But now what weekday is it halfway around the world? Now you need to look up their solar day.

All this to say - abolishing time zones will introduce the reverse problem for every problem that it seemingly solves. You can’t change the fact that our planet rotates and people in different locations will follow different schedules. Turning the lookup-table upside down is just a cosmetic change that doesn’t remove the situation that’s causing the confusion. I’d rather just stick with the set of problems that we’re already used to dealing with.

No

Maybe I’m missing something, but I think this doesn’t print or otherwise reproduce its own source code, so it’s not a quine afaict.

reserves the right to sell you out

Is Canonical actually doing that, though? Collecting data for product improvement purposes and collecting it to potentially sell to third parties are two wildly different things, and doing the former, even with the user’s consent, does not mean you automatically reserve the right to do the latter (or anything else, really) with the collected data, unless you explicitly already include that as an option and get consent for it as well. I haven’t looked into it myself, so I might be wrong here, but I’m guessing Canonical would be getting way more shit for this if they were actually reserving the right to outright sell the telemetry they’re collecting, rather than just use it for product planning and development.

Even I myself am not gonna remember how to use my tool a couple months down the line, unless it’s something I use very regularly.

Edit: noticed I read the comment I’m replying to wrong, reworded to make more sense

Not really self-hosted in the typical sense, but Obsidian with the Tasks and/or Kanban plugin synced through a (self-hosted) solution of your choice could work?

Haven’t tried the whiteboard tool in Google keep (didn’t even know there was one), but the Excalidraw plugin for Obsidian should cover almost any whiteboard use case I can think of. A bit more limited but also good is the native Canvas plugin in Obsidian.

It’s not only IPs and emails though. Since users can put whatever they want in comments and posts, all of those must be treated as potential PII, and have to be included in subject access requests and deletion requests.
