No.
That's not the same behaviour. You're literally lying.
The behaviour described wasn't "kicking people for low DPS" or "kicking people for pulling by mistake". It wasn't to do with kicking at all.
The behaviour being described is not just rushing through dungeons, either, it's specifically trying to play dungeons like they're M+, trying to use elaborate or risky skips in N/H dungeons and so on. That has never been normal in any expansion pre-BfA.
I've literally never seen nor heard of this happening, and I've done countless thousands of dungeons over the last few years. As a tank, I'm not particularly fast - but I've never been kicked or threatened with a kick for being slow (or indeed for any reason, except once in the very early days where I was kicked to make room for someone's guildy, after I didn't drop group immediately when the demanded me to).
