this thing has no replay protection
They added SIGHASH_UNIFIED after hard-forking.

If i understand how it works correctly, it's not complete/full replay protection. It seems, only BIP 110/BTC2B coin TX with SIGHASH_UNIFIED have replay protection. BIP 110/BTC2B coin TX without SIGHASH_UNIFIED and Bitcoin TX (that doesn't violate BIP 110) are still vulnerable to replay protection. CMIIW.

You're correct and that's how it's supposed to work.

So if you want to sweep, you need to sign your BIP110 txes with SIGHASH_UNIFIED.

correct, and that's what they can do. They can't add replay protection to sha256 chain, but as some ppl have claimed you can use bigger opreturn or you can first move coins on blake2b chain using replay protection if that's anyone's concern at all. But if blake2b is irrelevant to you and blake2b is worthless acc. to you then why do you care about any of this. Makes you wonder why gmax is inclined to lie and deceive everyday.
