I was speaking about the first version of "SegWit" which did not require a hard fork. The second one "SegWit2x" does, but wasn't pushed because of a lack of consensus and other technical disagreements.

Which lead us to my point. Even though there are concepts and technical similarities as you stated between the chains, one can mistakenly conclude that our situation is the same as the one on the bitcoin chain.

We should not, in my opinion, deal with the issue with an approach that plays more on the similarities of technical concepts, but rather on the different values and effectiveness of these concepts on different architectures and blockchain models.

That transaction consensus constitutes a higher threat to chains that are highly similar to our chain, thus, such technicals characteristics need to be taken into consideration while approaching the question of freezing stakes or any other form of transaction refusal. As you can see, a technical concept can carry different weights according to which environment you put it in hence why a precision could be made when writing about such a thing.
