This is where things are heading, especially for business or corporate 'consumers':
Need web hosting? Certainly you can't deal with a 2Tbps DDoS attack, so let's route that traffic through Cloudflare.
Sending email? Can't send it out with those /23s you have, they're on some blacklist from a shady DNSBL provider. Need to pay for GSuite or Office365.
Can't protect your CEO against a targeted attack? GSuite Advanced Protection or Microsoft ATP has you covered.
