The first thing that came to mind when I saw this project wasn't scraping (where I'd typically either want a less detectible browser or a more performant option), but as a browser engine that's actually sane to link against if I wanted to, e.g., write a modern TUI browser.
Banning the root library (even if you could with UA spoofing and whatnot) is right up there with banning Chrome to keep out low-wage scraping centers and their armies of employees. It's not even a little effective also risks significant collateral damage.
it is trivial to spoof user-agent, if you want to stop a motivated scraper, you need a different solution that exploits the fact that robots use headless browser
It's also trivial to detect spoofed user agents via fingerprinting. The best defense against scrapers is done in layers, with user-agent name block as the bare minimum.
I don't think they are using our browser :)
But in my opinion, blocking a browser as such is not the right solution. In this case, it's the user who should be blocked, not the browser.
