It will scale eventually, much of the problem with the transaction fees at this point in time is companies are not optimizing the code or their fee structure and paying way too much. Exchanges especially are charging way too much when they could get away with a much cheaper fee.
Maybe it was the exchanges doing the spam attacks in order to push segwit and off-chain scaling through. I bet Coinbase and Blockstream are under lots of pressure from the banks and governments to take complete control of Bitcoin. Now that they've penetrated the blockchain with segwit, it looks like the banks are winning. So sad.
I totally agreed. It doesn't make sense for an exchange to make a spam attack because eventhough they can charge high fees, customers then will go and look for better exchanges. And you can't say that banks are winning, we have no proof they the exchanges are being pressured by the government not unless they do like fake volumes or fake transactions. Although the spam attack has lessen to some extent now, we don't know will the people behind it will strike again. Maybe they ran out of steam because doing it cost as much money as well.
