1) Trying to put Bitcoin under centralized control;
2) lack of technical understanding.
ya.ya.yo!
Actually - I think (know) that if Blockstream wanted to, they could implement a system that was as good as bigger blocks.. almost overnight (without the complexity of Sidechains / Lightning etc..).
1) Only include the txn hash (not the whole txn) in a block. (Everyone already has the txn)
2) Prune all the SpentTXO from the data.
Then a 1 megabyte block could hold 10-20 times more txns.. and the blocksize / total-data would increase only 'marginally' (as the UTXO grows). It really is that simple.
I rate blockstream, go for it lads, but I feel that they are playing this situation badly. They could EASILY get everyone onboard, but are choosing not to..
..
In fairness, they are behaving like every other techie I know.. lol.
