I haven’t thought much about this so don’t take my view as definite but I think there are fundamental issues with any kind of link between Safe Network and the insecure internet. I’m sure people will build and use gateways, but they will I expect always introduce risks that will be be hard to mitigate.
So personally I’d rather maintain two areas. One which I know is insecure in a multitude of ways, and one which is very secure indeed outside of the device I use to access it, which I can then focus on keeping secure according to my needs.
If you aren’t overly concerned about security of your data on Safe Network, by all means use a bridge.
As for chat and other apps, we will always face the problem of inertia, but if things carry on the way they are there’s going to be a steady rise in the number of people choosing to use Safe Network because of its security and privacy characteristics, and adding gateways is a whole different market because it all but negates them.
What are the reasons to use Safe Network without security and privacy? In the early days, not many I think. Later when there are lots of apps and users, people will come for many other reasons, but for now our concern is early adoption, so I don’t think gateways are a sensible solution.
