*sadly goes to reset the counter to 0 on the "days since I saw someone shit on the existence of light themes" sign*
I think on average I see this like once a week.
I cannot see dark themes at all. And it's a hell of a thing to see this hostility not just to a software option but to my own existence and qualities as a person who uses this option. Like I've seen people say you have to be a psychopath to use light theme, which is an awesome way to double up on the ableism!
Something else about light themes I don't think I've seen in so many words:
I strongly suspect most apps these days are made for dark theme, in dark theme, by people who only like dark theme. The light theme sometimes doesn't work great, or it feels grudgingly implemented, half-assed.
The dark themes you see probably are optimized by people who care about them but don't think that means the light ones are. They aren't necessarily ideal for people who need light themes; this is just all we get.
Having just been talking about poorly-designed light themes this morning, I'm delighted to see that @Tusky updated for me this evening and its (already perfectly good, I hasten to add that this isn't one of the grudging, bad ones I was talking about!) light theme looks even better now! Better contrast. :) Hurrah.
@wolfie@bright_helpings@Tusky so glad to see it's helped someone. I submitted that change to Tusky and wasn't ever sure anyone other than me was really bugged by the not-very-light light theme. I have eyesight deterioration that makes dark themed things pretty unreadable myself but it's always felt like nobody else cared much.
@vertigo@wolfie@bright_helpings@Tusky it has been there for ages but it defaults to dark, not the system preference. Around Tusky 10 the light theme contrast got a lot worse though. In 14 it's properly light again.
