I feel the same way.
I may or may not obtain my books without DRM and then read them in a disposable qube without a netvm or on an airgapped hardware ebook reader. That way nobody knows when i am reading my books and potentially malicious epubs cannot create great damage.
If anonymity is the goal: Yes.
This is called k-anonymity. K is the number of people you look alike, so the more people look like you, the more anonymous you are.
Tor Browser has the goal to let every Tor Browser user look alike. If you are using Tor Browser without Tor somehow, that would make you stand out as likely nobody does that for example.
If your adversary has the ability to run code on your machine, there is absolutely nothing you can do to cover your tracks. Howevery it is unlikely that the surveillance capitalism adversaries like M$, amazon or google run code on my FOSS machines.
It totally is and this is arguably the goal of all this. A good keyword for more information is the Panopticon. You can start seeing this self censorship pretty much everywhere. People start to self censor in fear of being prosecuted for what they say, even if it is totally legal. Staying anonymous is an (more or less) easy way to avoid that problem.
There are degoogled androids out there one can use.
It should (imo). But it is not. You can be assured, that the “normal” people are much more vulnerable to mass surveillance that than you as a qube user are. You are using pretty much state of the art INFOSEC protective equipment against pwnage of your end device.
The fact that you think about things like that alone and consciously act (not meaning self censorship, but OPSEC considerations) make you hop out of the bell curve.
