@Suiseiseki Your source doesn't prove anything to me.

About network requests, they have previously explained what each are for.

About CloudFlare, your source suggests it applies to their webpages and can be mitigated by not using them as a homepage.

About unique ID, this has been explained as the least intrusive way to count installs and active users. I believe it's for their partnership business model and I accept this given I use their value-added services at no cost (gratis).

I will not enshitify my experience for the sake of ideology.
