It's indeed the terminology that rather new users or interested users use for some reason. When I am approached by someone I know, they often ask me what I think about cryptocurrency. Most of the time they do not specifically refer to bitcoin, but they mean bitcoin because I ask them "you mean bitcoin?", and the immediate answer is "yes bitcoin". I wonder if this has to do that a good bunch of the media use the term cryptocurrency.

But your concern is on point because if I were to tell those people who approach me that "cryptocurrencies are amazing and have huge potential", then me using the term might mislead them into searching for some low market cap shitcoin that could go 10,000x like bitcoin did. I do correct them or I put it into the right terms and let them know that there is a huge difference between bitcoin and 99.9% of the other coins.

I am not a 100% bitcoiner because I think a coin like Monero could have a right to exist. But to make sure that they don't get started with absolute garbage and then one day argue that "crypto" sucks but never owned any bitcoin, I am precisely pointing that out.

I haven't paid too much attention to it, but I believe that in this forum most of the older forum members tend to not confuse bitcoin with cryptocurrency as a general term for all coins in existence. It is usually the freshmen I guess who permanently talk about crypto instead of bitcoin, and maybe they are referring to anything that has a blockchain and they don't get the important difference anyway.
