That's how Microsoft markets their "safe links" in Outlook, which is more or less the same behavior of wrapping all links with a redirect. Whether they actually do anything with that to save you from phishing attempts or whatever... who knows. Even if there is a safety feature, it's still an easy way to mine url query params for data or learn about the user for other purposes (which they may or may not be doing)
IMO if you can't turn it off, there's a secondary motive to the feature. Especially when the feature is marketed from a place of fear rather than aid.
Gnome Tweaks, dconf UI or cli, or extensions can adjust all of those things, CSD included. I wish it was more baked into the settings, fwiw. One of the first things I do is move the CSD buttons to the macOS location.
I definitely agree the baked-in CSD is annoying at times, but now that Wayland has matured a lot and most apps have adjusted to baked-in CSD along with adding Wayland support, it's pretty rare to run into problems.
Also... if you've only tried gnome recently on Ubuntu, def recommend trying it on debian or another distro that doesn't drastically change everything about it.
(And of course, all that said, desktop choice is wonderful and no one has to settle for anything, big or small ๐)
