He technically did the cleaning. He screwed up because he didn't consider what the point of cleaning was (like you say, giving her wife a day off) and he just did something that he thought was approximately equivalent to what she literally asked.
I call that "not really caring". If he cared, he would have realized he should have cleaned the day before and given "a clean bathroom on Mother's Day" as a present instead of "the act of cleaning the bathroom on Mother's Day".
I call it "not really understanding". The cleaning was most likely more work than a few more phone calls to cleaners for quotes would've been. If it was about not caring then why wouldn't the husband put in the minimum effort and get in someone else to do the cleaning?
In the article she mentions that she controls the budget, so it was probably over the budget he had to work with.
To be honest, the author's culture is alien to me and I only have stereotypes (TV and movies, mostly) to go on.
Read the article again. This is the key part...
"I was gifted a necklace for Mother's Day while my husband stole away to deep clean the bathrooms, leaving me to care for our children as the rest of the house fell into total disarray."
If the idea behind Mother's Day is to give mothers a day off, can you see why the gift of getting cleaners in would've worked, but the gift of offering to do the cleaning did not?
