There are various reasons why (some) VPN are blocked. These reasons are usually connected to protecting a business model, but are not that much related to ads. They are also not explicitly directed against privacy-sensitive users, this is more an unintended side effect:
Some sites block VPN because they are used to bypass geograhic restrictions. This is ...

Well try to think how a security sysadmin of a commercial site could think. Their site receives a number of connections, most of them are fully legitimate, but some may not be. If they are just providing info at no cost using advertising as their main business model, they generally do not care much about VPNs.
But when they expect the peer to buy something ...

Great question. What you are referrer to is known as OpSec or Operational Security which looks at multiple steps that need to be taken from the OSI model right down to the social and privacy consideration that could allow for attribution.
To maximise anonymity you will need to have a layered approach. This can consist of multiple different layers including ...

Commonly, the same mechanisms as in the browser. Very often applications use a API made available over https. It's cheap to implement, well supported and fairly robust.
Even if not using http, it's common to use TLS to secure the traffic. This includes protocols such as imaps, smtp+starttls and so forth. TLS is a common and widely supported protocol, that ...

Using a VPN with Chrome is not the same as using TOR. Your VPN provider knows your IP, and can also see which sites you are visiting. With TOR, there is no one entity that can see both.

I know where to look and I'd been to the darknet forum myself. You need to use the TOR browser because that forum will block all types of browsers. But I don't know if I should mention the name here in public since that will encourage illegal activities.
As for the methods, they are using various methods. For example, they are using Linkedin API to scrap the ...

I don’t know where to look.
How they are sourced - usually they are put up for sale. Eventually someone leaks them and their value goes to zero. So they ask for a high price and that alone makes noise on forums.
Once they are leaked they are on forums, but torrent, and places like that.
The rest is more info on what an information security person needs from ...

I will skip the points around why you cannot be fully private with WhatsApp or evangelize you moving to Signal/Session/Etc. as you appear to already be cognizant of all of this.
In terms of what you can do:
Request a copy of your data to understand what they have on you, more information can be found here https://faq.whatsapp.com/general/account-and-profile/...

Short answer: yes, they can still track and profile you in most cases.
Theoretically and technically CDNs and other websites can profile or track you trough images and normal (cached) requests. For example ETags and caches can be used for this too.

ETags can be used to track unique users, as ...

There are ways to trace incoming calls to see who is calling, even when they spoof the caller ID.
Use Whitepages website for a reverse phone number.
Yellowpages can also work, if you suspect a business phone number calling you.
Spydialer can tell you what type of connection was used Cell phone / Landline, and you can look up their name and listen to ...
