Wow they made a 7 nm chip when everyone else is already at 5 nm and its physically impossible to get smaller because of quantum tunneling...
Mock my ass.

Mock is a strong word. They don't care how we feel about it actually. They want the technology. They've developed it. That's not mocking that's competition
They didn't develop the machines needed to produce the chips, yet. They bought the lithography machines from the only producer - dutch ASML, but that's now cut off. The news is kinda overblown.
7nm node is a marketing term and non-Chinese companies have been making this chip generation since 2016.
Samsung and TSMC have been making 5nm generation chips for almost three years now.
So yes, there may be a technological/sanctions aspect to China having homegrown 7nm production but:
They are still years behind the rest of the world, it's unclear how good these 7nm chips actually are, it's unclear what their volume is, or their ability to improve further.
This is the best summary I could come up with:
Chinese social media users are having fun teasing the U.S. government and the (in)effectiveness of its technology sanctions on chipmaking equipment.
Significantly, much of this advanced new tech may never have been developed and produced in China if the US hadn't imposed its far-reaching sanctions.
As a field grows fertile after a bloody battle or a phoenix rises from the ashes – Huawei has achieved the kind of comeback that nobody would have expected a few years ago.
Additionally, US-sanctioned Chinese chipmaker SMIC has been under more pressure than ever to develop and refine its semiconductor manufacturing.
SMIC’s manufacturing line is also based on new tech, namely Twinscan NXT:2000i deep ultraviolet (DUV) lithography scanners.
Sanctions might have a place to retain advantages over rivals, but nuances of their application must be learned from the newfound vitality of blacklisted firms like Huawei and SMIC.
