Hey I'm the author. I definitely didn't mean to imply you should remove critical system apps (I don't think that's possible on vanilla iOS).
More just that it's worth deleting most apps beyond the basics like calls,text,calendar,maps etc
hey nah I don't (it's a very new blog!).
In the future though I'm considering purchasing and writing reviews of specific "dumb phones" like the Nokia 6300 4g. There's an affiliate marketing angle there, and I'm also considering creating Youtube review videos too.
