You have freedom of speech, that doesn't mean that these companies have to give you a platform to do it. DailyStormer disgusted enough people with their actions, that the companies that they rent services from decided that public pressure could affect their future profits by association. There was most likely a clause in the contract that allowed them to close accounts for any reason at all and DailyStormer agree to that. If most of your opinions are hateful, I have little sympathy if people stop working with you - that's their choice.
As for your idea for new tech, you're essentially asking for someone to come up with a better version of the internet so.. good luck with that
And yet, as disgusting as they be, Freedom of Speech, is foundational to a free society.
I'm typing this on an ASUS. If ASUS disagrees with what I say should the censor me? Should there be keylogging on each computer and have everything you write be reviewed to see that it is approved by the powers that be?
If ASUS shouldn't then why should any ISP?
