But what we can do is be the change we want. Just make my own little oasis. Find other oases and hook ‘em all up.

While I agree with everything you wrote, the nuance is that not everyone can make their own little oasis. That doesn't make a complaint about a lack of oasis invalid.

And even for those who can, the vast majority of time spent on the internet is consuming content, not creating it, so it's perfectly logical to lament the lack of the little oasis that used to exist.

I’d love a browser that I switch into Web Classic Mode and it pretty much only reaches these resources.
