There’s a lot of common patterns, but you have to understand how URLs work. You have to recognize which URL parameters are tracking ones or even just might be tracking. And that means you have to know how they work and that takes a moment.
In brief, URL parameters start after a ? in the URL and are formatted like key1=values&key2=value2. You can’t usually remove all parameters because not all are tracking. To further complicate things, URLs can also have an anchor starting with a # character which will be after the URL parameters. You often don’t want to remove that (though theoretically the anchor could in fact contain tracking details).
It’s often trial and error to see which parameters you can remove. I do this a lot since I write a lot of technical documentation. Clean URLs make the documentation more compact and less likely to break. It’s not just tracking stuff, but sometimes you need to remove temporal data that makes a page display data from a specific time when you want it to just default to the current time (etc).
The cult of personality thing is the big part IMO. If it was just him being a piece of shit without any influence, then whatever. But he has a cult following that are influenced by him and his actions (plus Twitter seems now designed to push his thoughts). It’s important that the vast majority of people understand that Musk is an idiot and a piece of shit. It needs to be lame and gross to like him.
