That's like saying email spammers aren't abusing anything, they're just using the system as it was created. Allow me to rephrase your statement: "If you have a problem with email spam, then where were you when email was invented"?
email and bitcoin. two different things. i don't really need to explain why do i?

to you maybe they are spamming the bitcoin network but to me it looks like they are supporting it. maybe they should be using OP_RETURN instead of creating unspendable outputs but that's their perogative because i guess segwit can let them do anything they want to. maybe we should get rid of segwit, what do ya think?
