AITA for refusing to pay for my sister’s wedding after she insulted my "boring" job?

I (27F) work in high level data cmopliance for an international logistics firm. Its a specialized role, and honestly, it pays extremely well, just think mid-six figures. My sister Steph (24F) has always been the creative & free spirit of the family and frequently makes digs at my boring corporate life and how I have no real passion.

Steph got engaged alst month. My parents are retired and can’t afford a big wedding, so I privately offered to cover the venue and catering (about $25k) as a gift. Jess was thrilled until last weekend at a family dinner.

She started talking about her wedding vision and then said, "I'm so glad I didn't end up like you, sitting in a cubicle all day just for a paycheck. It must be so sad to have a job that provides zero value to the world." I was stunned. I told her, "Well, that 'value-less' job is currently the only reason you aren't getting married in a park with Costco pizza." She called me elitist and said I was "holding my money over her head."

I wasn't able to hold myself back and now I’ve now rescinded the offer. I told her that since my corporate money is so "tainted" and "soul-crushing," I wouldn't want it to riun the vibe of her "authentic" wedding. My parents are now calling me the AH, saying I'm being petty and "ruining her once-in-a-lifetime moment" over a "small comment." Jess is currently blowing up my phone saying I'm "financial abusing" her which makes no sense.

AITA for taking back the wedding gift after being insulted?
