Welcome!
I don’t know about the big boys and I’m also not a tech geek, but generally speaking here are a few things it will mean for people running online businesses:.
- I think you will be able to just drag and drop your site on the SAFE network, so porting over couldn’t be much easier in that respect. [EDIT: see below, only true for static sites. Otherwise they need re-writing].
- Sites on SAFE also only need to pay once, rather than having an annual hosting fee like on the internet.
- You can’t do denial of service attacks on SAFE (no server to spam) so that would be a godsend and big money saver.
- The site would scale positively, so the more users accessing it the faster it would load, rather than lagging when trying to buy tickets for Glastonbury etc ;).
- You could conduct frictionless, feeless, instant, secure and private transactions - also suitable for IoT. So that has pretty huge implications for anyone running any online business.
- No central stored data as a point of failure to be attacked.
I’m sure that’s only scratching the surface, but those would be good enough incentive for most businesses if there were customers to be acquired on SAFE.
Yeah, but people do want freedom. People don’t understand that this is what privacy and security really are. They don;t need to understand it though, they just need to see that they need SAFEnet to do many things they can’t do on the legacynet - think how simple whistleblowing and running services like wikileaks could become. 300M people a day use bittorrent. several million a day use Tor etc. How many Ashley Madison users and dark market buyers etc would rather have a simple and robust solution.
Also, think how important this kind of robust security is for governments etc. Seen the Snowden film? Nuclear power plants, water treatment centres etc, these all need robust security. The US could turn off the power in Denmark. Do you think the Danish like that now that they know?
Make no mistake, privacy and security may not sound sexy, but they ARE freedom. You can’t have one without the other. So in actual fact they are very cool, popular and powerful incentives, even if people might take a while to understand that.
All the privacy and security stuff out there now is a pile of plasters (band-aids to our cousins from the US). SAFE is the foundational solution. It solves the root problems rather than just trying to tackle the consequences of a poor infrastructure.
Anyway, that’s enough from a non-techy like me. I’m sure I’ve given you a bit to think about and given you good reason to search out more informed and intelligent posts than this one to help you dig deeper down the rabbit hole 
Nope, we have a lovely beaker browser and it is a beaut!
