People don't seem too upset about this, so I'll go off in another direction! The Youtuber doesn't understand basic capitalization, in titles or sentences, and even the channel name is botched. To add some irony, the channel has "Learn" in its name.
I'm not expecting English majors be consulted for every statement, but the most basic grammar, that small children learn, is certainly not too much to expect from an "educational" channel. That's bottom-of-the-barrel, and they still can't be bothered. Hell, there are dozens of websites that you can just drop text into, and the site will automatically fix your capitalization, instantly, for free.
They describe themselves as an "advanced level" education channel. You can't even get away with that kind of sloppiness in junior high, so the actual channel "level" is likely below that. If they can't be bothered with such a basic detail, we should not trust anything else they have to say.
Apologies for the digression, and the rant. This is mildly infuriating, but I feel better now.
