Thank you for this hint!
Sorry, I was not able to find this myself due to bad german translation of the article's title.

Looking for the sweet spot of blocking and not blocking I found so many posts on the web where users struggle with this. And I don't understand the necessity of this.
Why let almost every new Pi-Hole user run into trouble with so many commonly used services and not do something about it? Just include this whitelist and give a hint how to deactivate it if needed.
Fun fact: I wasn't able to pay with paypal for my Pi-Hole patreon account until I found out that js.braintreegateway.com was part of a blocklist. Why hurt yourself this way?
On the other hand I wonder why blocking the tracking of smart TVs isn't part of the default blocklist set, for example. That was one of the most important arguments for family & friends getting a Pi-Hole.
Sooner or later most users will find this list and end up copying it into Pi-Hole blocklists section, no?
Why not include a longer list of blocklists and give the user the option to select/unselect those in the setup process?
