but you didn't address my question
Multiple web browsers have embedded PDF viewers because the PDF viewing experience for most people sucked so much. That's not a product decision taken lightly.
Your personal experience does not reflect that of many other browser users, it seems. Even on mobile I dread clicking a PDF link.
But it's nowhere close to the complexity of the entire web stack, not within an order of magnitude. It's much, much simpler.
I'd respond to the rest of your vague and incorrect opinions, but why would I do that if you're not even going to bother to address my points despite me asking you to repeatedly?
If I must spell it out, there you go:
> Why was I forced to install a substandard, feature-poor, ridiculously slow pdf viewer that I never wanted and which took over as the default pdf viewer against my wishes and without asking me, just because you couldn't be bothered to install a decent one?
Because you are part of a minority of Chrome and Firefox users and I'm probably part of the majority of users, in this regard. I don't know this for sure, but if a Google program manager decided to back building and embedding an entire PDF reader into a browser, I'm 99% convinced this is true.
We're dumb and you have to live with us.
Life's tuff.
