3. The group saying both at the same time. This was short lived and was very messy mainly seen in SegWit2x which had its own separate issues.
Slightly off-topic, but this group (as in anyone who support both off-chain and on-chain upgrade) is alive and well although most of them aren't in hurry for block size increase. And i wouldn't even categorize SegWit2x in this group when it was more about politic rather than technical issue.
Their forum is dead too

Bitcoin.com has gone full scam and is now promoting Ethereum and a Bcash sidechain called Smart BCH in order to keep scamming people by selling them worthless tokens on their Uniswap clone called Verse DEX.
--snip--
This is first time i heard about BCH sidechain. It's really weird when BCH itself already have ETH-like smart contact capability[1] and it's not like their block constantly full[2].
