I think it matters.
I use the like as an acknowledgement & agreement. I will not like something that I would rather have not seen.
I use the zap to signal that i derived some value from the note.
A like is an Event in Nostr, in the same way a note is. It is me expressing my agreement without having to type it out.
If you want to abandon likes (not see them or use them), you can always use snort.social
