Personally, I love server-side rendering, I think it's the best way to ensure your content works the way YOU built it. However, offloading the processing to the client saves money, and makes sense if you're also planning on turning it into an electron app.

I feel it's better practice to use a DNS that blocks traffic for known telemetry and malware.

Personally, I used to blacklist all scripts and turn them on one at a time till I had the functionality I needed.
