At the moment, the world of Browsers is currently a big Monopoly favoring Google: Chrome is the most widely used Browser in the world (Some say, even 70% of all users use chrome: https://en.wikipedia.org/wiki/Usage_share_of_web_browsers#Summary_tables).
Chrome has a so called Engine at its core. That is the thing which actually understands websites and can translate that to something you as a user can see and interact with. This engine is called Blink. Many other Browsers such as Opera, Internet Explorer, Brave, etc also use Blink.
That means, the developers of Chrome (=Google) have much power over websites, because they control how users see the websites.
The only other engines (and therefore truly independent browsers) are Gecko from Firefox and WebKit from Safari. Firefox however is also dependent on Google and is currently badly managed. (=The user share of firefox declines, the payment of the CEO is rising).
Furthermore, all these browser engines are written in insecure languages. (=Because when these were started, more secure languages didn't exist yet).
Servo is a browser engine, which started at mozilla (the company developing firefox), but it was discarded. Servo was then moved to the linux foundation and the open source consulting company iagalia (https://www.igalia.com/2023/09/07/The-Servo-project-is-joining-Linux-Foundation-Europe.html). So it is truly independent and its progress is promising!
I feel LaTeX is not a replacement for inDesign. It would be a replacement for something like word. maybe try scribus?
