As others have pointed out, having so many Proton apps might be an issue. However, that line of thought only works if you’re really concerned about having a single point of failure. Most people value convenience much more than that.

The way I see it, this setup is somewhat noob-friendly, but relying heavily on Proton makes it a lot more convenient for many people. Using a greater variety of providers would make sense, but you can’t expect everyone to be ready for a hassle like that. People seem to expect you to be a hard-core privacy warrior who is willing to make significant sacrifices for philosophical reasons.

Most people aren’t like that. Just switching to DDG is hard enough for them, but at least it’s a step in the right direction.

If you take only 1/10th of this diagram, you get the simplified newbie version. Take all of it, and it’s for a person who is clearly interested in security and privacy. Modify a few things here and there, and you get a version for a serious security enthusiast. Different versions for different audiences.
