ASICs didn’t really take over until around 2013 (I was designing some PCBs for one of the first ASICs in 2012)

All tokens are effectively "slaved" to the BTC tokens due to paper thin real liquidity of all of them. Therefore GPUs were very much affected by the BTC volatility, just via proxy, and likely still are. It should be obvious really for anyone.

Litecoin and Doge and Ethereum were mined on GPUs throughout that period. And in fact all the other coins are tied to bitcoin in the first place, bitcoin price runs also trigger huge mining booms in everything else, so yeah, it's kinda understandable that people tend to view them as a single linked thing, because they kinda are.

What, precisely, is the point of making "actually you mean crypto, not bitcoin" posts, other than demonstrating that you are, indeed, "very smart"? Like, this person doesn't even exist, it's just a "heh aren't those no-coiners dumb" strawperson that you imagine to be some big dummy.
