I have both my HPWC and NEMA 14-50 listed on Plugshare. If someone is travelling northwest from Toronto, there are no SC and very few other charging options. In the winter, in particular, I've had Leafs and Teslas both use it. I suspect they would have struggled to get home. Interestingly, a few Volts too....
It's a "commercial site" (My horse barn/ riding lessons etc.), so it's both community service and a bit of advertising. While waiting for a charge, they can have a coffee, and watch the riding lessons, or use the wifi.
I have no concerns about security.
