As much as I want to agree with you, the people who like TikTok make up a significant amount of the population, and their opinions do matter--arguably more than yours, due to sheer numbers.

Smugly dismissing them doesn't do you any favors except for making you feel good about yourself for a few seconds.

I feel the same way every time I read that someone did something "quietly" in a headline.

Yeah, this is an incredibly common metonym.

Personally, I'm diametrically opposed to the idea of letting Google dictate how web browsers must function, which is what happens if everyone uses Chrome (or a fork) and web developers start targeting features that are only supported by Chrome (and its forks).

The question is not "Is Opera a valid choice instead of Chrome?"

The question is actually "Is Chrome, or anything that's based on it, a valid choice?" and the answer is "no."
