Hanlon's and Occam's razors point to it being a mistake by the GFW operators, imo.

If it's on purpose, I think you have the most likely motivation.

You shouldn't use razors haphazardly or you might cut yourself.

A mistake that also weirdly increments some TCP fields for the three subsequent RST packets when that's not how the existing GFW devices behave would need some explanation before you could conclude it to be the most likely explanation.

A new hardware/software rollout is one of the more common breakage situations, though. It definitely could have been on purpose but my gamble is still on a fuckup with a new system rollout.
