Yes, like I said, I didn't think denigrating Anki was specifically Fernando's purpose here.

However the reason I find it off-putting is because, as someone who generally lives in the terminal, and Anki is one of the few remaining GUI apps I rely on, I actually "would" have preferred a decent terminal alternative with similar features. But introducing the alternative by saying how much Anki sucks immediately puts me off when all that criticism doesn't resonate with me.

It literally works as anti-promotion here: if Hashcards promotes itself as missing all those features of Anki which I think are great, and my time is limited, then I have much less of an incentive to invest the time to check it out. Which is ironic, because in reality it may be great (like most of his other work) and actually suit my use-case really well.
