Of course I mean pure ungoogled Chromium, without bloat on top.
Not only browser code consists of millions of lines, it is also audited by thousands of people, and, importantly, changes can be highlighted, which doesn’t allow for them to go unnoticed.
Successful mass attacks with OSS typically require much more skill and resources as you need for you malicious code to be written in a way that stays unnoticed (and eventually, rather soon, it will be discovered, with all consequences).
With closed source programs, integrating malicious code is easy, and this code can stay there unnoticed for ages, so they are 100% “trust me bro, I don’t do anything bad”.
So, yes, OSS is more secure.
(not me downvoting)
I understand the concern with locally made software. However, I’d rather see something open-source come from the US than something closed source come from my own country.
Speaking of Konqueror, what about Falkon? It is the newer option by KDE team, and works on a more modern engine. And, it works on Windows.
