Initially it was promoted as Bitcoin Core with a 2 MB block size limit patch, and now they've started implementing some strange features (SPV mining). Obviously the advertising was misleading ad best.
segwit AKA core AKA blockstream AKA PwC AKA corporations and banks initially was promoted as a malleability fix.
yet.
they added RBF.. at the same time as promoting segwit, thus fixing malleability (to make zero confirms trustworthy again) is again a futile thing to do again
meaning people can still mess with transactions before confirmation and no one should trust zero confirms even after segwit.
then they tweaked it to bloat up the transaction while not delivering more capacity, then they realised that the tweak could allow more capacity as a sideeffect,
but.. then they want to bloat up the transaction with payment codes rendering nodes unable to act as a transparent ledger that can account for funds because the funds are hidden.
then reinvent the node as being a lite no witness pruned edition so that there is even less chance of being a full node..
core is as bad as classic.. do not blindly trust any corporate controlled dev team. and trust me that $55mill of blockstreams is not just being used by a couple people who have no control of the code.. atleast think logically,
