alt Hacker News>Gmail isn’t even the worst offender, it’s just a more popular one. The Tesla and Crypto.com apps are around 1 GB each.
One reason is those are typically apps which need to be heavily secured. So behind the seemingly "simple" user interface and functionalities, there's so much security related code to ensure their "safety".
More importantly, it's difficult to code without dependencies.

Generally the larger the codebase the harder it is to secure. I am less worried about security vulnerabilities on small tightly focused apps than I am on gigantic monstrosities with hundreds of different attack surfaces.
According to looking at a 1,000 line code file on my machine right now, a million lines is about 48mb. You think > 10 million lines of code are required for security in an app?
Pardon? I can't tell if you're serious. How would adding more lines of code in a program (or assets or whatever make up this size) add security?
