I agree that it usually doesn’t add anything to the meme, especially nowadays. It’s a pretty low-effort template.

I like Know Your Meme’s description:

a phrasal template used to mock people who strive to attract attention and tend to provide unsolicited opinions, as well as for observational humor.

I think its original usage in mocking attention seeking was funnier. It’s basically generalized into any observational humor though, which is when it becomes unnecessary.
