Why would a spammer use OP_RETURN if it's cheaper to use Witness data to store arbitrary data?

Because of all the drama, I'm adding another reason to this:
A potentially concerning reason would be a group of emotionally charged people who didn’t get their way with Bitcoin's direction on the datacarrier flag. They are willing to burn money and act against their economic interests to try to prove themselves right, at least in the short term.

OP_RETURN data is signed by the signatures in inputs, and therefore cannot be malleated, while at least the signatures in witness data are malleable. Some users also perceive OP_RETURN as the "correct/righteous" way to embed data.
OP_RETURN outputs are also slightly cheaper for small data payloads up to 143 bytes, but more expensive for bigger data payloads.
