Dang. Not the company I was hoping.

If they’re using an eero router, I’m going to assume you’ll just have an ethernet cable from an ONT then into the router. Ask the installer if you need to use the eero or can you install your own router. That may alleviate some of your concerns.

I work for an ISP and self host. I have more things in place to track my usage than any ISP would put just because I make myself the guinea pig for new equipment and want to know exactly what is happening. You will never use a full 8 gig (at least as of now, obviously in the future that will change). If the extra money isn’t an issue do it, but if you can “girl math” the $30 price difference, stick with that for a year and spend the extra $360 you saved on multi-gig networking equipment, that’s what I’d do.
