I'm wondering when copying becomes just following industry best practices...
Twitter, Threads, Mastodon, Blusky all look the same. Project management apps all reuse the same UI patterns. The "AI" logo looked pretty much the same for all companies for a while. Video sharing websites all use YouTube's layout. Forums like Reddit and HN share quite a lot in their looks.
If you want to display website analytics, you will want to show the most important metrics at a glance, you'll need graphs showing visitors over time, top sources and pages... There is only so much you can do to display those and have users understand what's going on on your website.
It's not just the looks that are the same. The UX / mechanics are way too similar too, e.g. how you can apply filters (by URL, by referrer, by browser, etc.) to narrow down the stats view.
I would say pretty much the idea is as follow: "Let's do it so User would know how to use it before we are big", and once you're big enough - you can set the trend. But at the beginning it's just not worth it and highly risky
