It is, and "RAS syndrome" (redundant acronym syndrome syndrome) should be encouraged, not avoided.
"PIN number" is easier and faster to understand. Probably better understood than "PI number" or the expanded form. And in this case, a link just named "fish" would have been fairly ambiguous.
RAM memory
DVD disc
LCD display
We like our nouns to be general, and rather turn the acronym into an adjective. It makes good sense too: PROM memory, BluRay disc, OLED display show their connections
Your first example is a recursive acronym (actually a backronym in this case), and is deliberate. That's the trope. Redundancy is usually just incorrect but common use of natural language.
Edit: I'm wrong about WINE being a backronym, but it is a recursive acronym.
> Redundancy is usually just incorrect
How is it incorrect?
Perhaps a weaker way of putting it is that it is colloquial, but not proper form.
> not proper form
Which is annoying to those who value form more than function.
Isn't this a common trope with software e.g. "WINE is not an emulator" or people saying "ATM Machine".
