I think “20 minutes ago” is a lot more useful than seeing the full date on every comment and having to do mental math. It does make it harder to see the precise date, but that’s a far less common use case, so the tradeoff goes towards making it more usable for the more common scenario. So I see that as the reason: it’s usually better. The full date is still available on hover, which seems reasonable to me.
I disagree with your premise that web developers “want to make it hard”, as that isn’t the motivation. The motivation is to make it easy to see when a comment was posted, which is far more useful as relative time. That it makes it harder to copy the full date is not the goal, but an unfortunate side-effect of the tooltip disappearing when you stop hovering over the relative time. Which I’m sure you could submit as an issue to the lemmy devs, because likely it just never came up, and isn’t some evil plot to “make it hard on purpose”.
Yeah, I’d rather play on my deck instead
