Please take this in good faith, as I hope your own post is, but I interpret the thread you're replying to as focusing on the "everyday' part.

Share knowledge? I don't think anyone here is arguing against that in any way (or conversely arguing for hoarding knowledge).

The concern, one I share, is where the sharing has to happen publicly "every day" - so no matter how trivial, useless, niche, overly-specific the tip is (whatever, the list isn't exclusive), someone shares it.

That's the part that's not sharing knowledge for the benefit of others, but rather self-serving. I might even go so far as to say self-serving doesn't even need to be selfish; the person might genuinely believe they're doing good, but even there, self-serving.

TLDR: Share your knowledge, don't make sharing something every day, even when you don't have something valuable to share, your target.

PS - if this note irks anyone (are routine maxxers a thing?), make the goal to learn something every day, then share where appropriate.

Yep, crop dusting knowledge in a public space without at least tying it to something relevant is a faux pas in my book.

Offering to teach someone something proactively? Sure, go ahead.

Sharing stuff freely when asked and arming someone with the tools to investigate further? Amazing!

Treating a public channel like ye olde facebok wall? Mildly annoying.
