We can. Individual sites still exists. Simpler pages still exist. In some way, wikipedia is a large project that's mostly "old school" (despite many attempts to change that). Old communication tools still work, mail can still be done with ease by small or even individual providers. Forums are still a thing in some communities. RSS to get informations about many sites in one place still exists and never stopped existing (it's surprising how many recent websites still implement it). Some people still use IRC and newsgroups on a daily basis.
I'd even argue that google search, the old, simple, easy one, still exist. Look up udm14, set this in your browser, and your done. And contrary to the apparently largely accepted trend, this one still gives great results.
Firefox, despite recent attempts (that will probably keep coming) can still be trimmed to be a basic browser for the most part. Large surface to open an HTML page, bookmarks, tabs on top (fancy), and nothing else in the way. I don't know how long this will persist, but it's still possible.
There are many things that are still around, the presence of huge behemoths in the front row doesn't change that. The only difference is that using the web in this manner requires a bit of involvement and a bit of work. When it was the only way to do things, people got involved and spent effort to do so. Nowadays, with large services providing one click stop to seemingly everything, most people won't put up the effort to look somewhere else. And they don't care about the consequences of this centralization on privacy, bias, censorship, etc.
But a lot of the old web is still available. Heck, even old reddit is still around (although the content itself is still reddit).
And it is a simpler life. Taking back control of our digital activities requires some minor involvement, but not being crushed by the endless content and notification machine is real nice in this overstressed world.
