That is nice but consider a broader point of view please:
If not carefully choosing offline-only software, then almost everything demands internet access nowadays. All of those things will claim that they handle my data safely. Obviously that cannot be true, leaks do still happen.
So from the perspective of someone who has to actually install, use and frequently update a dozen of Android apps, it is much easier to stick to only using such which do not want internet access instead of constantly having to read a very large amount of changelogs because all software you use is hooked up to the internet.
